Pollution is the ugly byproduct of civilization, a pox on the land and your Sims' bodies. Though it's impossible to outright stop pollution, you'll need to reduce it as much as possible to minimize problems among your city and region.

Types & Causes of Pollution

Pollution comes in several forms. The most common is air pollution , which is generally produced by coal power plants and oil power plants , dirty industrial buildings, and bad traffic . Air pollution can spread across the region , so an especially dirty city can actually pollute an otherwise totally green city. Within one city, air pollution travels in the direction the wind blows, which can carry it into a residential area.

Ground pollution occurs because of poor waste management and sewage solutions. Sewage by its nature is pollution, and the areas around sewage outflow pipes will always be dirty (though the areas around sewage treatment plants will be clean if it can handle the load). All zones create trash, and if it's not picked up, it'll turn into ground pollution. If you bulldoze a landfill, all trash converts to ground pollution, dirtying the ground and turning it an ugly black, as you can see in the screenshot above.  Ground pollution disappears gradually after several weeks.

Water pollution is created when your water tower or water pumping station is sitting on an area that is infected with ground pollution. This is actually the worst type of pollution because all Sims will be affected by it, and its effects are more pronounced because the Sims are literally ingesting the pollution.

Radiaton Pollution is created when a nuclear power plant is bullzoded, staffed with unskilled workers, or explodes. It can also be created occasionally by a meteor strike . Currently, there is no known way that has been confirmed to reduce radiation pollution. Radiation pollution is a type of ground pollution, and any spot infected with radiation will be shown as maximally concentrated ground pollution. Radiation pollution goes away after about 20 in-game years.

Effects of Pollution

Pollution causes several problems in cities, though some are pretty subtle. The most obvious issue that the land becomes pretty gross to look at. You'll see brown clouds floating through the air or even across the region. A thick brown cloud can block the sun, thus lowering the power output of any solar power plants , including a solar farm in a great works site.

The most direct issue that pollution causes is illness. The presence of pollution in any form causes germs to run rampant through the city. Sims who get sick call off work (lowering the happiness of industrial zones) and don't go out to shop (lowering the happiness of commercial zones). If it lasts too long, Sims will die; even if not, this puts pressure on your healthcare system and delays the advancement of your city.

You can fight germs with a well-designed and well-funded healthcare system. Don't skimp on adding ambulance modules to clinics and hospitals , and invest in some wellness vans. These drive around the city at random and scrub down buildings they stop at, preventing any germs from forming there for a short time. With many wellness vans operating, you'll be able to destroy the majority of the germs that form. You'll never be able to stop all germs, but reducing as many as you can will keep your hospitals running efficiently and ensure that sick Sims get the treatment they need.

Fighting Pollution

The mere act of having dirty buildings or traffic causes pollution, which is why you can never eliminate it; you'll never be able to achieve 100% mass transit use, though you can come close. With smart placement of buildings and investments in services, you can at least make pollution a non-factor in your city.

The first thing you should do is ban yourself from using dirty power plants. Stick with a solar power plant, wind power plant , nuclear power plant , or simply buy power from a neighboring city.

If you consult the zone attributes charts, you'll see that the biggest polluters are industrial zones with low tech levels. If you want a green city, you'll need to invest in education early. Consider applying the department of education and Department of Utilities modules (in that order) on your city hall when you can. This way, you can quickly get access to education and sewage solutions. Place a community college or university as quickly as you can, and get those tech levels moving.

Meanwhile, start planning your mass transit strategy . Create long avenues without intersections that are conducive to streetcars, and plan where you'll place your passenger station or ferry Terminal if you have rail or sea access. Although traffic doesn't have as big of an impact on pollution as buildings do, the effect can be significant.

Finally, add some parks . Not only will you be increasing the land value and encouraging wealth level upgrades , but every park slightly reduces overall air pollution. Adding a small park on every block will significantly lower overall city pollution and help your Sims breathe easier while still keeping the land relatively pure.

If you add parks, it's best to put some near the industrial zones and the residential zones. If you can only afford one or the other, place them downwind of the industrial zones until you can afford more. It won't help nearby house land values, but it will absorb more pollution if that's your priority. Still, plopping a billion parks is a less permanent solution than taking out the building in the first place; always prioritize education to make dirty industries irrelevant.

Parks are also not cheap, having a lot in city can cost more than all other utilities. Parks also absorb the ground pollution they sit on, meaning the sims that visit said parks will get sick from the ground polltion. A park can acutally get a lot of sims sick if placed in industral areas or anywhere that has ground pollution, be smart with your placements of parks, it may help to aleviate air pollution but can get sims sick by absorbing ground pollution.

Micropolis! is an iOS-exclusive idle city building game from Everywear Games, that is optimized for quick gameplay sessions. The game boasts of a simple and intuitive design that removes all of the usual clutter that come with city building. In fact, the developers take pride in this game’s playability on the Apple Watch. In this game, you are of managing a city through the ages. You will need to construct buildings, level up houses, and expand your territory. As your people progress through the different eras, you will be able to unlock different technologies. You will also have access to different skills that will help you progress even faster in the game. The game has four different ages that you need to play through in order to create your own unique city. Complete the list of challenges in order to receive numerous rewards. Managing an entire city can get frantic as you progress. It’s a good thing you can rely on our Micropolis! cheats, tips and tricks to help you through it!

1. Understand The Interface

Decluttering the game is great because it becomes playable on different devices. Unfortunately, it comes with a few setbacks. One of which is the minimal guidance you get for what the things on the screen are for. Take a good look at the screen and learn everything so you can better understand the game. First off, the circular bar next to a building’s level is the milestone bar. Fill it up in order to activate a multiplier. The top bar indicates how much money you need for the next level while the yellow bar on the bottom indicates when you will receive the next payment from a particular building.

2. When To Spend Your Money

Since this is an idle city builder, you will actually earn a lot of money while offline. When you return, the first thing you should do is spend all that money on buildings. There are several ways for you to spend all your earnings. One way is to prioritize the most expensive buildings since they earn the most. Just quickly tap on your high-earning buildings to immediately buy the maximum amount. You could also opt to spread the money evenly among your buildings. Just make sure you invest everything you can before logging off in order to maximize your offline earning potential.

3. Claim Your Free Gift

Every few hours, you will receive a free gift from the game. These are often boosts that you can use on the buildings to improve revenue. Just keep swiping to the right until the main menu appears. You will see a gold gift icon if your free gift if available. Otherwise, it will just be a grey box with a timer on it. Make sure you use up all your boosts on your best buildings to get the most out of them.

4. Complete Those Quests

Micropolis! offers several quests for you to complete. Doing these quests will reward you with various boosts and perks. Most of them are easy to achieve since they only involve reaching certain milestones in the game. You will be able to complete these by playing normally. You just need to check back on the quests from time to time in order to claim the rewards.

5. Hold Off On Advancing

Reaching a population of 1,000 for the first time will allow you to advance to the next era. This will reset all your progress but will also give you boosts in gameplay, similar to how prestige works in most other idle games. The higher your population is prior to advancing, the more boosts you get. Make sure you wait for as long as you can before advancing to maximize the boosts you can get.

Prepare to guide your city through the ages in Micropolis! Just follow the tips and tricks we listed above and you will be advancing in no time! Also, if you have any other hints for the game, don’t hesitate to leave us a message in the comments!

Micropolis - A New Name For a Classic City Simulator Game

Remember when SimCity first came out? When you sank days into what by modern standards is a simple simulation? Nothing quite like it existed before, and it took the world by storm – and killed more than a few of your weekends. Well, you can experience the original city simulation all over again – free of charge. Micropolis is a free city simulator you'll almost certainly find familiar – but it's not just some clone.

Remember when SimCity first came out? When you sank days into what by modern standards is a simple simulation? Nothing quite like it existed before, and it took the world by storm – and killed more than a few of your weekends. Well, you can experience the original city simulation all over again – free of charge.  Micropolis is a free city simulator you'll almost certainly find familiar – but it's not just some clone.

In the 1980s Will Wright designed a city simulation, and called it Micropolis. The first game released by Maxis, Micropolis' name changed before release...to SimCity. The momentum of that franchise continues – a fourth sequel was released just this year .

But that's not the entire story - in 2008 Will Wright released the source code for the original game under the GPL 3 license. The game was donated to One Laptop Per Child, but the nature of open source means anyone can edit the code of or simply play the original SimCity – free of charge. Trademarks being what they are, the game can't be called SimCity...so it's called Micropolis. It's available in most Linux distros, and a Java version opens the game to everyone else.

Playing Micropolis

Launch this game up and you'll have the distinct impression the game's been redesigned. Don't panic: this new landing page is the only example you'll see of this sort of aesthetic. You can start your new city or choose a scenario – but no one ever plays scenarios. Start a city.

micropolis city simulator

When you do you'll be presented with the SimCity you know and love. Sure, the interface is a touch dated, but everything works just the way you remember. I was able to build a post-industrial hellscape in a matter of minutes.

If you're unfamiliar with the original SimCity, don't panic - it's not that complicated. You need to build roads, power infrastructure and zone lots. Do well and people will move into your city, do poorly and they'll abandon it, leaving you with no revenue and a lot of useless roads to maintain (similar to some actual cities, actually). It's a game about balance above all else.

city simulator

The fun of the game comes from keeping everything running - revenue, crime, transportation, entertainment. Help prod the city to growth, and remember, you need more police stations than you think.

You can also help growth by adjusting the budget. There's not a lot of control – at least, not compared to modern incarnations – but it's interesting to see what effect tweaking things can have. Raise taxes and people will leave, lower taxes and you won't be able to fund anything.

As mentioned earlier, you can also play various scenarios. I enjoyed the layout of Hamburg – it roughly corresponds to the real city – until it was bombed to oblivion.

micropolis game

In this scenario the goal is to continue rebuilding in spite of constant Allied bombings. You can also rebuild Tokyo after a Godzilla invasion or a futuristic Boston after a nuclear attack ("future" as in 2010, amusingly enough – man this game is old).

So yeah, everything you remember from the original SimCity is here – because that's exactly what this is.

Installing Micropolis

If you're a Linux user, good news: it's really easy to install Micropolis. Just check your package manager of choice and you'll almost certainly find it.

Everyone else can download Micropolis from Google Code . Getting this working will require Java, but couldn't be simpler if you do. Just download the ZIP, extract and run the JAR. Here it is on a Mac:

micropolis city simulator

Some people will tell you to avoid Java – there's a case to be made against installing the platform . But if you want to play Micropolis on Mac or Windows, it's your only choice. The secure choice, as always, is to simply switch to Linux.

There's also an online version of the Micropolis city simulator, but I couldn't get it to work. Let me know if it's just me.

If the new SimCity leaves you in any way nostalgic for a simpler game, Micropolis is worth checking out. It's not the only alternative out there, however -  we've also outlined modern alternatives to SimCity . Be sure to check them out if you can't get enough of simulations.

Are you guys digging Micropolis? Let us know in the comments below, and please, share any other amazingly retro games that have been open-sourced. I love learning about stuff like that.

Scientists find way to remove polluting microplastics with bacteria

Sticky property of bacteria used to create microbe nets that can capture microplastics in water to form a recyclable blob

Microbiologists have devised a sustainable way to remove polluting microplastics from the environment – and they want to use bacteria to do the job.

Bacteria naturally tend to group together and stick to surfaces, and this creates an adhesive substance called “biofilm” – we see it every morning when brushing our teeth and getting rid of dental plaque, for example. Researchers at the Hong Kong Polytechnic University (PolyU) want to use this sticky bacteria property and create tape-like microbe nets that can capture microplastics in polluted water to form an easily disposable and recyclable blob.

Although these findings, presented on Wednesday at the Microbiology Society’s annual conference , are still preliminary, this invention could pave the way for sustainably lowering plastic pollution levels in the long run by simply using something found in nature.

“It is imperative to develop effective solutions that trap, collect, and even recycle these microplastics to stop the ‘plastification’ of our natural environments,” said Sylvia Yang Liu , microbiology researcher at PolyU.

Microplastics are the plastic fragments, usually smaller than 5mm, which are accidentally released into the environment during production and breakdown of, for example, grocery bags or water bottles – or during everyday activities such as washing synthetic clothes such as nylon or using personal care products with scrubbing microbeads in them.

Although they are tiny, the risk they post to the environment is huge. Microplastics are not easily biodegradable, so they stick around for long periods of time and they also absorb and accumulate toxic chemicals. They disperse into wastewater and into the oceans, endangering marine animals who end up eating them and eventually trickling into the food chain and harming human health too. Microplastics had been found in more than 114 aquatic species in 2018, according to the International Maritime Organization , and they have been found in salt, lettuce, apples, and more.

Yet, there are not any sustainable, one-size-fit-all ways to eliminate microplastics.

With this research, Liu and the team led by Professor Song Lin Chua and James Kar-Hei Fang have engineered a bacterial biofilm, from a bacteria called Pseudomonas aeruginosa , able to immobilise and incorporate rogue microplastics floating around in the water. These microbe nets trap and group the microplastics and make them sink to the bottom of the water. Then, thanks to a “capture-release mechanism” using a biofilm-dispersal gene, the researchers can unlatch the microplastics from the bacteria traps and find themselves with bulks of collected microplastics ready to recycle.

“This is a really innovative and exciting application of biofilm engineering to address the plastic pollution crisis,” said Dr Joanna Sadler , researcher at University of Edinburgh, who was not involved in this study. “One of the biggest challenges in dealing with microplastics is capturing such small particles so they can be degraded and removed from the environment. Liu and co-workers have demonstrated an elegant solution to this problem, which holds great potential to be further developed into a real-world wastewater treatment technology.”

However, the experiment is still preliminary: it has been carried out as a proof-of-concept test in a controlled lab environment and not in the ocean or the sewers; and it was done using the “aeruginosa” bacteria strain, which is a disease-carrying bacteria for humans and probably could not be used in large-scale projects. But the researchers are confident that the method can be replicated to find natural biofilm-forming bacteria directly in sewage or other watery environments and go from there.

“In terms of the capture of microplastics, it’s an interesting development,” said Dr Nicholas Tucker , senior lecturer in molecular microbiology at the University of Strathclyde, who was not involved in the study. “Whether it’s scalable is going to be interesting to see.” According to Tucker, there will need to be more research on what types of surfaces to grow the biofilm on.

However, research like this provides a good example of the many uses for microbial biotechnology and what big feats tiny bacteria can accomplish. “In general, this shows that microbes can and will play a role in every stage of the life cycle of plastics,” Tucker said.

Solving Microplastic Pollution Means Reducing, Recycling—and Fundamental Rethinking

New practices, and new chemistries, are needed to end the scourge

By Andrea Thompson

This is the third of a three-part series that examines our growing understanding of the scope and impacts of microplastics pollution.

At several locations around London last winter and spring, researchers stalked the streets counting the number of discarded plastic water bottles they encountered, as if tallying species across a coral reef.

Their aim was to see if a new initiative to enlist businesses where people can refill empty bottles with tap water was making a dent in the trash littering the pavement, says marine biologist Heather Koldewey, who oversaw the research. Bottled water use has doubled in the U.K. in the past 15 years. And notably, plastic bottles are abundant along the banks of the River Thames, which carries them out to sea as they gradually break down into ever smaller fragments, tainting the river and the ocean with microplastics that can invade every level of the food chain.

Scientists have found these tiny bits of degraded plastic—along with fibers shed from synthetic fabric, and microbeads from cosmetics—lurking throughout the oceans, lakes, soil and even the air . Creatures from plankton to earthworms to humans are eating them, posing a potentially serious health threat to animals and ecosystems. The problem is only expected to balloon as plastic production increases exponentially—from a mere two million metric tons annually in 1950 to more than 300 million metric tons today, and a projected 33 billion metric tons each year by 2050.

To get the microplastics problem under control, the world has to take three primary steps, those who study the issue say. In the short term society needs to significantly curtail unnecessary single-use plastic items such as water bottles, plastic shopping bags, straws and utensils. In the medium term governments need to strengthen garbage collection and recycling systems to prevent waste from leaking into the environment between the trash can and the landfill, and to improve recycling rates. In the long run scientists need to devise ways to break plastic down into its most basic units, which can be rebuilt into new plastics or other materials. “There’s definitely no single solution,” says Koldewey, of the Zoological Society of London and a National Geographic Fellow.

REDUCE AND RECYCLE

An attractive, low-hanging target for tackling microplastic pollution is the drink bottles, utensils and bags that are called single-use plastics. Because they are used for convenience, not necessity, they are easier to do without, and the polymers used to make them are among the most commonly produced and found in the environment. Bans are becoming an increasingly popular way of curtailing their use, and limited evidence indicates they do reduce debris. But as Koldewey and others point out, governments that impose bans need to consider: whether such measures are cost-effective; what the environmental impacts of alternative materials might be; and what roadblocks such as, in the case of bottled water, a lack of places to fill up a reusable bottle might hamper the effectiveness of a ban.

Koldewey’s own campaign to reduce the use of bottled water in London, called #OneLess, studied possible locations for placing refilling kiosks that would get the most use, such as public transportation hubs. The group also conducted surveys that found most residents would prefer to get water from the tap but were uncomfortable asking stores or restaurants for a free refill. The initiative to sign up businesses that would allow people to refill their bottles was aimed at overcoming that reluctance. Addressing such potential barriers is crucial to changing people’s habits, Koldewey says.

Reducing single-use plastics will help the environment because the packaging sector more broadly is the biggest user of plastic polymers. But plastic, including some of the same polymers found in single-use packaging, is also used in construction, electronics and fabrics. The latter are the source of microfibers, which are proving to be one of the most ubiquitous forms of microplastic pollution. Scientists are concerned that focusing on single-use plastics will obscure more systemic issues around plastic that need to be addressed. “It’s a super-useful first step,” says Martin Wagner, an ecotoxicologist at Norwegian University of Science and Technology. “What I’m afraid of is that that will be it.”

His worry is well founded. In Europe only 30 percent of plastic is recycled, whereas in the U.S. it is a measly 9 percent. “Our waste management systems are good, our use of them is pretty lousy,” Koldewey says. The need to expand recycling capacity in places like the U.S. is becoming acute now that China—which has imported 45 percent of all plastic waste intended for recycling since 1992—has closed its doors, leaving many Western countries with nowhere but the landfill to ship their discarded plastic.

One key aspect of improving recycling, some experts say, is designing products so they are easier to recycle. Plastic is typically recycled by shredding it, melting it down and molding it into new plastics. But other chemicals added to improve product flexibility or durability, or to simply add color, make it difficult to recycle and reduce the quality of recycled plastics. “We’re taking some of what are potentially our most recyclable polymers and rendering them unrecyclable because of inadequate or inappropriate thought at the design stage,” says Richard Thompson, a marine biologist at the University of Plymouth. As an example of a potential remedy, he cites Japan, where all polyethylene terephthalate (PET), used in plastic bottles, is transparent. Clear PET is much easier to recycle than when coloring is added in. “It’s possible to do it,” he says.

RETHINKING PLASTIC AND RECYCLING

Curtailing the use of plastic and improving recycling and waste systems would put a major dent in the plastics entering the environment, but not every plastic is easily recyclable and some will still likely make their way into rivers, soil and seas. In the long term some scientists think changing the very nature of the material and the methods of recycling it could be the ultimate solution to the plastic problem. “We need a much more fundamental change in our approach,” Wagner says.

For years materials scientists have been trying to create plastics that will biodegrade. Today plastic that is labeled biodegradable can actually only be broken down in specialized facilities that heat it to high temperatures. “In an aquatic environment, in your backyard compost pile, that’s not going anywhere,” says Sherri Mason, a professor of chemistry at the State University of New York at Fredonia.

There is a fundamental tension to creating truly biodegradable plastic, because a polymer that will completely degrade into carbon, oxygen and other elements in a lake or soil would not be particularly useful as packaging, say for keeping food on a shelf for months. “There’s a central problem around what we want versus what’s realistic,” says Andrew Dove, a chemist at the University of Birmingham. Thompson thinks biodegradable plastic may need to be confined to products only needed for a short time that are then discarded, such as burger wrappers at sports stadiums or utensils at fast-food restaurants.

What Dove and a growing number of materials scientists envision to reshape our relationship with all plastics is to move from physically recycling plastics by grinding them up to chemically dismantling them to weed out all the impurities that taint recycled plastic. Such a method would take a PET bottle, for example, and break it down into its most basic molecules, separating out added chemicals to provide the building blocks to remake virgin polymers. In this way plastic would become its own perpetual raw material, the way glass and paper are (although the latter are physically ground up, not just chemically broken down). “With some plastics, there’s no reason why you can’t infinitely recycle,” Dove says. “People just haven’t looked at it. It’s not been considered something that’s important.”

For the polymers that cannot be unraveled into their most basic molecules, Dove thinks it should be possible to at least chemically break them up into other small molecules that could be used for different purposes, such as fuel or pharmaceuticals. Ideally, scientists would devise chemical reactions that did not require too many harsh compounds and are not too expensive. That would give value to the plastic waste that currently has no, or very little, value. Currently, “it’s much cheaper to burn them or to throw them away in landfills, and that’s the core of the issue,” Wagner says.

Making discarded plastic valuable could also provide incentive for cleaning up the plastic waste already in the environment. “If we can create something high-value from cheap plastic waste, there might be an economic argument to go and dredge this out of the ocean,” Dove says. “We’re a long way from that, but that’s what we’d like to achieve.”

A few scientists have already begun to look at ways to clean up some of the microplastic waste, which could remain in the environment for at least several hundred years. Cleanup is difficult because the plastic particles are small and varied in nature, and the ecosystems in which they are embedded are vast. Researchers have found enzymes and bacteria that can break down certain types of plastic, but they need to figure out how these might be deployed without any potential negative side effects, such as producing greenhouse gases. Agroecologist Esperanza Huerta Lwanga, of Wageningen University in the Netherlands and the College of the Southern Frontier in Mexico, for example, hopes to test whether earthworms that possess plastic-munching bacteria in their guts might be able to remediate soil littered with plastic from the burning of trash.

While those methods are being developed, cutting off the flow of plastic is key. Doable steps need to be taken now. “The bottom line,” Thompson says, “really is that all of this [pollution] is avoidable.”

Listen to the article

  • Macroplastic pollution has been catching global attention and mobilization but microplastics are still lagging in terms of regulatory and corporate action.
  • There needs to be more awareness around the impact paint and tyres have on microplastic pollution as they are the leading sources of environmental leakage.
  • May 2023 negotiations around the UN Plastics Treaty in Paris present an unmissable opportunity to set legally binding global measures to address microplastic pollution.

With every new piece of scientific research, the scale and impact of plastic pollution become ever more glaring. We are eating , drinking and breathing microplastics; they are raining down on us and are even found in breast milk and fed to our children .

The impact plastic pollution has had on planetary and human health is, therefore, abundantly clear. The year 2023, however, holds major opportunities for the global community to bring about positive changes for plastics and the ocean.

Have you read?

Microplastics in the food chain: how harmful are they, plastic pollution: european farmland could be largest global reservoir of microplastics, the problem.

Microplastics are entering human and planetary ecosystems through several sources:

  • Primary intentional microplastics. These are made for use in cosmetics, personal care products and more.
  • Primary unintentional microplastics. Such microplastics emerge due to wear and tear or may come from paint – identified as the biggest source of microplastic leakage worldwide in a 2022 report – followed by tyres , textiles and pellets.
  • Degraded macroplastics or secondary microplastics. They involve plastic products, packaging and single-use plastics that break down in the environment.

Research suggests the average person eats at least 50,000 particles of microplastic a year and breathes in a similar quantity. The true number, however, is likely to be much higher, as only a small number of foods and drinks have been analyzed for plastic contamination .

The consequences such microplastics have for human health have been exposed; for example, Taiwanese scientists found that consumption of microplastics had negatively impacted brain health and memory in mice.

Scientists have also established links between everyday exposure to chemical additives that leach from plastics and impaired reproduction, brain health, obesity, diabetes and some types of cancer. The effects are evident in babies, children and adults of all ages.

And t he European Commission has concluded that the growing scientific evidence on the hazards of uncontrolled microplastic pollution, combined with its long-term persistence and irreversibility, suggests that reasonable and proportional measures should be taken to prevent the release of microplastics.

The solution

Despite the exponential growth in initiatives and regulations to tackle plastic pollution, there is no sign that leakage rates are slowing. For the most part, industries responsible for plastic production and its subsequent pollution seem not to have engaged in solving the problem and, rather, seek to maintain the status quo. Therefore, solutions should take a regulatory shape to drive corporate action.

Regulatory action could enforce product labelling requirements to inform customers of the risks of mismanagement, solutions available and ultimately, "extended producer responsibility," which requires producers to report their plastic data.

In March 2022, the United Nations Environment Assembly unanimously adopted Resolution 5/14 , “End plastic pollution: towards an international legally binding instrument.” This resolution was an important milestone and a major leap towards a plastic-free ocean.

The framework will be negotiated through a series of global meetings and is expected to be in place by the end of 2024. The preamble to the resolution highlights that “plastic pollution includes microplastics,” hence the Intergovernmental Negotiating Committee will need to consider how to address macroplastic and microplastic pollution in the global agreement.

A recent Nordic Co-operation report highlights the opportunity for the UN Plastics Treaty to tackle this urgent problem and to address microplastics as a distinct category of plastic pollution, warranting specific control measures.

Microplastics are different to macroplastics in many important respects. These include:

  • Tracking and monitoring challenges.
  • Higher toxicity due to their chemical composition.
  • Potentially higher human, plant and animal risks.
  • Different regulatory solutions and control measures.

They are also a significant problem in their own right. For these reasons, microplastics should not be treated as secondary or subsidiary to macroplastic pollution.

In addition to the regulatory route, we need to look at ways to reduce demand for plastic products, make available alternatives that are accessible economically and at scale and provide adequate waste and recycling facilities.

We also need full supply chain accountability and resource circularity. And since production and consumption patterns are global, there is a need for cross-sectoral and cross-value chain collaboration.

Looking ahead

The year 2023 will hopefully see three positive developments in microplastics.

Firstly, the EU Commission will publish its report on microplastics and the regulatory measures it will implement to achieve the EU Green Deal objective of reducing microplastic emissions into the environment by 30% by 2030. Strong regulatory signalling should drive action by the paint, tyre and textile industries to engage on this issue. It will also provide a more solid basis for innovators and capital to develop new solutions to tackle the problems of secondary microplastics.

Secondly, the Pew Charitable Trusts will publish an update of their 2020 “Breaking the Plastic Wave” report. They have indicated that it will highlight paint as an important source of microplastic pollution along with solutions.

Recommendations from experts like Pew on microplastic emissions will drive policy changes and regulatory action.

Finally, and importantly, the second round of negotiations on the planned UN Plastics Treaty will occur in Paris, France, in May. The meeting presents an unmissable opportunity to set legally binding global measures to address microplastic pollution.

Plastic packaging and single-use plastics have gained a place on the agenda at the UN Plastics Treaty negotiations, partly because big retailers and consumer goods companies face customer pressure to act on plastic pollution.

The same consumer pressure is not felt by paint, tyre, plastic, chemical and textile producers, whose products cause a large part of microplastic pollution. Therefore, governments and regulators must bring those industries to the UN Plastics Treaty negotiating table to account for their products’ significant negative impact when they end up in the environment.

If we don’t deal with microplastics as part of the new global plastics treaty, we will have missed a critical opportunity to tackle this pervasive problem that jeopardizes the health of people and nature alike.

Micropolis Cheats: Tips & Strategy Guide

The world is a capitalistic pursuit, and it is time to chase it!  Micropolis   is an idle city building game where you construct different kinds of buildings to earn gold! The more buildings you have, the more gold you will get, and the bigger your cities will get! Our Micropolis cheats and tips will show you how to make a ton of money and advance through eras!

Micropolis, like most idle games, is about settings the stage for your profits to come in before you leave the game. We will show you how to do that in our  Micropolis cheats, tips and tricks strategy guide!

Complete your tasks!

While it may not seem like it at first, Micropolis actually features a length city building campaign. To keep yourself on track, it is best to follow the active tasks. You can see your task list at any time by tapping the star at the top left corner of the screen. You will always have four tasks active at any given time, so be sure to work towards at least one of them.

They will often have you upgrading a certain building to a specific level. Every time you complete a task, you will be rewarded with something special, whether that be plain old gold or a skill!

For added convenience, you can see a building’s next milestone indicated by the purple star at the bottom of the screen. Milestones are most often what you will need to bring the building to in order to complete a task.

Get the random bonuses!

Every so often when you are looking at one of your buildings, you will see a purple button appear. A meter around the button will start to empty out, while the money shown in the middle of button increases.

Wait until the meter is about to be completely empty, then tap to claim the money! The longer you wait, the more money you will earn, but watch out – if you wait too long the button will disappear!

This random event happens fairly often when you have the game open, so with some luck and good timing, you can make quite a bit on money out of nowhere!

Use couriers and workers effectively!

Remember that Workers boost a single building by a significant amount, and Couriers boost three different buildings with a weaker effect. Also keep in mind that these two skills cannot stack, so effective placement is the key to efficiency!

It is best to spread the Courier across your middle-income buildings, while the Worker should be on placed on your highest profiting building. Space them out so that they are not overlapping to get the best effect!

Check your Supervisors!

Supervisors are even more permanent passive bonuses to your buildings, but first they must be equipped. You will sometimes gain them upon leveling up a building, so keep an eye out. Each Supervisor is exclusive to that building, so do not worry about having to spread them around to each of your buildings.

That’s all for Micropolis! If you have any other tips or tricks to share, let us know in the comments below!

How to fight the microplastics and micropollutants health hazard

The vice-president of the European Investment Bank, Ricardo Mourinho Félix, shares why efforts to regulate the use of microplastics and micropollutants must be accelerated.

Image placeholder

Ricardo Mourinho Félix

Tackling microplastics and other pollutants in our soils, rivers, lakes and ocean has become an imperative . People who eat seafood regularly digest around 11,000 pieces of microplastic every year . About five grams of plastic particles enter all of our gastrointestinal tracts every week . That’s about the weight of a credit card.

Health risks on a planetary scale

For the first time in history, serious and immediate human-made health risks are unfolding on a planetary scale. Water pollution by microplastics and micropollutants is a serious emerging health hazard. Here we set out the extent of the problem and possible solutions to reduce the tide of pollution. Despite limited evidence on the adverse impacts of pollution from microplastics and micropollutants on human life, we need to increase public awareness of the health risks of ingesting these contaminants.

Micropollutants are small, almost invisible parts of products that are used daily, such as in pharmaceuticals, industrial chemicals, cosmetics and pesticides.Unlike microplastics, most micropollutants cannot be removed by conventional wastewater-treatment plants. They find their way into ecosystems and finally into our food chain. 

Microplastics, on the other hand, are tiny solid plastic particles that are increasingly polluting our rivers, soils and ocean. According to this EIB study , it is estimated that the amount of microplastics on the world’s ocean floor to date is at least 14m tonnes. 

At present, Europe and Central Asia together account for about 16% of microplastics released into the oceans. North America is by far the largest generator with 17%, followed by East Asia and Oceania (15%), according to the same study . The European Union’s share is estimated at 10% of the global total, or about 150,000 tonnes per year. Even though the European Union’s contribution to the emission of this pollutant is not the highest, 89% of EU citizens are concerned about the impact of plastic products on their health, and 88% are concerned about the environmental impact.

The limitations of wastewater treatment

Most microplastics can be retained by stormwater or wastewater-collection systems. In the European Union, conventional wastewater-treatment plants are an effective means of reducing pollution, as they can capture up to 99% of microplastics. 

However, conventional wastewater-treatment plants are unable to efficiently remove micropollutants such as antibiotics or other hazardous micropollutants from wastewater. A way around this is to upgrade current wastewater-treatment plants and implement a so-called “fourth treatment stage”. This might increase energy consumption by between 5% and 15% and entails additional costs for maintenance and treatment products to reduce the impact of wastewater pollution. To introduce this fourth stage in wastewater-treatment plants with a capacity of at least 10,000 person equivalents, the estimated cost would be around €2.6bn annually in the European Union.

Wastewater utilities in Europe do not have many incentives to invest in facilities that would reduce the release of microplastics or micropollutants into the environment, since the benefits of these investments cannot be captured in the form of higher tariffs. In addition, there is also limited information about the economic benefits of reduced microplastics pollution, since there are very few studies that have attempted to quantify these benefits. By contrast, there is a long list of benefits in terms of maintaining biodiversity and reducing risks to public health.

So how can we protect the ocean and our health?

Legislation, regulation and investment

It is crucial that the public sector steps up its regulatory role to foster the regulation of microplastics and micropollutants. That might mean stricter effluent-emissions standards, a credible system of fines for their violation, taxes on pollutants, and the provision of financing to the water sector on favourable terms.

The new Urban Wastewater Treatment Directive, a revised version of the current directive proposed by the European Commission, can help reduce microplastics pollution in the European Union further by requiring continued investment in new and expanded conventional wastewater-treatment plants and stormwater-management systems. Other concrete actions are being addressed with specific legislation such as a ban on the intentional addition of microplastics to products.

The total elimination of micropollutants in water is not a legal requirement in the European Union. This must change in the near future with the adoption of EU directives and regulations. Several EU states, notably France, Germany and the Netherlands, are already implementing policies that reduce micropollutants in treated wastewater through additional treatment stages. 

Greater public awareness of the issues relating to microplastics and micropollutants, sustainable behaviours, technological innovation, and more circularity in the economic models of production and consumption, is also crucial, since currently most of the available solutions address the issue at the “end of the pipe”.

All the measures to reduce these contaminants can help turn the tide in favour of the ocean, but also  benefit our health.

How to Fight Microplastic Pollution in Garden Soil

We can't fix the problem, but we can strive not to make it worse.

Microplastic pollution pervades every ecosystem on Earth. It is found in every ocean , in the soil, in the water we drink, the food we eat , and in our own bodies. This immense problem is not one that will easily be tackled overnight, and the effects on our health are, as yet, not entirely known.

Treehugger readers will surely wish to do all they can to limit the problem of plastic pollution. So, today, I thought I would talk a little about how we can, at the very least, limit pollution in the soil of our own gardens.

Avoid Synthetic Materials

Some common garden products are potential sources of microplastic pollution. I have written before about reducing plastic use in the garden, and this should always be your general goal when sowing and growing. 

But plastics in the form of synthetic fabrics—like horticultural fleece, for example—can shed particles more than the usual items we look at like plastic pots and bags. Synthetic twine or netting can also break down in the environment. Some paints used in a garden can also shed tiny particles into the surrounding environment.

Your gardening gloves are likely made from plastic materials, and likely a lot of the other clothes you wear for gardening, too. Synthetic fabrics shed fibers not only when they are washed, but while they are in use. So, if you really want to make sure that you are contributing to microplastic pollution as little as possible, natural clothing options are a good idea.

These may seem like small and insignificant actions in the great scheme of things (and of course bigger-scale solutions are needed). But anything we can do to limit microplastics in the soil in our gardens means healthier soil and fewer particles ending up on our plates.

Plastics accumulating in soils can have a negative effect on soil health, fertility, microbial activity, and plant growth. It has been demonstrated that the presence of particles can change soil properties such as soil aggregate structure, water-holding capacity, and microbial diversity and functioning.

What is more, scientists have shown that microplastics in the water and soil can make it into the foods that we grow and eat, which may, scientists believe, have a detrimental effect on our endocrine systems.

Don't Use Commercial Composts—Make Your Own

Unfortunately, there is no way to know how many microplastics are in commercial compost or other materials that you buy to use in your garden. Microplastics have been found in municipal composts and in others for sale.

You can have a little more control by making your own compost, carefully controlling what ends up in it. Home composts can also be a conduit for microplastics to get into the wider environment, so be very careful about what goes into your compost to help tackle this problem.

Avoid Microplastics Ending Up in Homemade Compost

Here are some sneaky sources of microplastic pollution to avoid adding to your composting system:

  • Plastic-coated paper and cardboard
  • Sticky labels on fruit and vegetable peelings 
  • Remnants of plastic packaging on food scraps
  • Tea bags (many of which contain plastic in the bag)
  • Wet wipes (which are often plastic )
  • Vacuum cleaner dust (with fibers from synthetic clothing, carpets, etc.)

Catch and Filter Runoff From Driveways and Roads

Another thing that you could think about in your garden is how to prevent water runoff from roads and driveways on your property from ending up in the wider environment. 

Car tires emit a dust containing microplastics when they rub on road surfaces, and this is another major source of microplastic pollution . Catching runoff and directing it into vegetated swales and rain garden systems can help in a small way to reduce the spread of those particles.  

The problem of microplastics is a major one and can be overwhelming. Nor can we keep them out of our lives (or even our bodies) altogether, since a high percentage of drinking water in both Europe and North America contains microplastics to some degree.

But by making sure we do all we can to limit plastic use in our homes and gardens, and by taking small steps to prevent tiny plastic particles from spreading through our gardens and the wider environment, we can at least strive not to make the problem worse.
