Plastic usage is a problem. We know this. We\u2019ve heard stories that plastic straws kill turtles, we have seen pictures of sea animals dying from plastic entanglement and each day, we see first-hand trash cans overflowing with water bottles and trash blowing down our streets.<\/p>\n\n\n\n

In response, many people try to limit the number of single-use plastics in their lives, to use compostable utensils and straws, to opt for reusable water bottles, and to recycle more. But we\u2019re only seeing a small fraction of the problem \u2013 and of the potential solutions.<\/p>\n\n\n\n

Throughout the life cycle (including production, usage, recycling, and pollution), plastic causes serious environmental problems<\/strong>, in addition to some health problems<\/strong>. New research shows that plastic pollution reaches almost all areas on Earth \u2013 from remote lakes to deep coral reefs.<\/p>\n\n\n\n

While some consequences are easily seen and understood, other consequences are more complicated and less obvious. The widespread impacts of plastic \u2013 both simple and complicated \u2013 have significant effects on human life as well as animals and the environment<\/strong>.<\/p>\n\n\n\n

Stage 1: production<\/h3>\n\n\n\n

Most plastic is made with chemicals that come from fossil fuels.[1]<\/sup> Plastic production, from fossil fuel extraction to plastic manufacturing, releases greenhouse gases.[2]<\/sup> In the EU, 20% emissions from the chemical industry are from plastic production \u2013 approximately 13.4 million tonnes of CO2<\/sub> a year.[3]<\/sup> Furthermore, experts expect production to triple in the next 40 years as demand increases.[4]<\/sup><\/p>\n\n\n

Stage 2: Recycling & Waste Management<\/h3>\n\n\n\n

The world has produced approximately 7 billion metric tons of plastic waste<\/strong>.[5]<\/sup> Plastic waste takes many forms \u2013 from grocery bags to water bottles to large items. The most common type of plastic waste, perhaps surprisingly, is cigarette butts which are considered plastic waste because of plastic in their filters.[6]<\/sup><\/p>\n\n\n\n

Unfortunately, of the 7 billion metric tons of plastic waste, we have recycled less than 10%<\/strong>.[7]<\/sup> Furthermore, recycling isn\u2019t easy, and the process releases greenhouse gases.[8]<\/sup> Plastic must be sorted by type before it can be melted down, but there now exist thousands of types, making this extremely difficult if not impossible.[9]<\/sup> There is no economic incentive to recycle plastic because recycling it is extremely expensive and costs more than producing new plastic.[10]<\/sup> Also, a lot of plastic poses toxicity risks because of the product itself or because it absorbed chemicals over its lifetime, so it should not be recycled or has limited possibilities (e.g. toxic plastic cannot be recycled into food packaging).[11]<\/sup><\/p>\n\n\n\n

If only a small fraction of plastic is ultimately recycled, where has all the plastic gone<\/strong>?<\/p>\n\n\n\n

Nineteen percent of plastic waste is burned, and 50% goes to landfills.[12]<\/sup> Incinerating<\/strong> plastic waste causes major air pollution from the release of toxic gases,[13]<\/sup> in addition to contributing to climate change with the release of greenhouse gases.[14]<\/sup> Plastic that ends up in landfills<\/strong> will take several hundred years to degrade, and as it degrades, the plastic can contaminate soil and water with toxic materials.[15]<\/sup><\/p>\n\n\n\n

If you have been doing the math, you probably realized there is still about 22% of plastic waste unaccounted for<\/strong>. This waste is mismanaged or pollutes land and water ecosystems.[16]<\/sup><\/p>\n\n\n\n

Stage 3: Land & Freshwater Pollution<\/h3>\n\n\n\n

Improper disposal of plastic is causing health problems in some parts of the world. When plastic clogs sewers and collects standing water in countries with inadequate waste management systems, it promotes mosquito breeding, among other organisms, and increases the spread of diseases like malaria.[17]<\/sup><\/p>\n\n\n\n

In the natural environment, micro<\/em>plastics (plastic pieces smaller than 5mm) can contaminate soil in a variety of ways; for example, there are microplastics in composts or municipal solid waste can degrade in soil.[18]<\/sup> Microplastics are able to both physically and chemically alter soil, in ways not yet fully understood by scientists.[19]<\/sup> <\/p>\n\n\n\n

Freshwater ecosystems also accumulate a significant amount of plastic debris<\/strong>, as it makes its way toward the ocean.[20]<\/sup> A recent study found Lake Lugano and Lake Maggiore in Northern Italy to both have more plastic concentrations than parts of the ocean considered to be the largest plastic-accumulation areas.[21]<\/sup> This amount of plastic is most likely contaminating the drinking water from the lakes with microplastics, in addition to harming lake ecosystems.[22]<\/sup> The paper also found that plastic has even been able to pollute remote lakes and freshwater bodies that do have direct contact with humans.<\/p>\n\n\n\n

Stage 4: Oceanic Pollution<\/h3>\n\n\n\n

The world\u2019s oceans act as the primary plastic \u201csink\u201d \u2013 the place where most plastic ends up<\/strong>.[23]<\/sup> This has a huge negative effect on coastal and oceanic ecosystems.[24]<\/sup>  At the base of marine food webs, a wide variety of fish that eat plants or plankton have ingested plastic, according to studies.[25]<\/sup> This means that as those fish are eaten by bigger fish, plastic begins to be distributed across the food web.<\/p>\n\n\n\n

On land, debris gets degraded and often breaks into smaller pieces. Once in the ocean, small pieces further degrade because of UV radiation from the sun.[26]<\/sup> Microplastics can have a variety of impacts on marine organisms, including reducing algae growth, creating blockages in fish, disrupting oyster reproduction processes, and hurting the rate of growth of corals.[27]<\/sup><\/p>\n\n\n\n

According to the July 12, 2023 Nature <\/em>article \u201cPlastic pollution on the world\u2019s coral reefs<\/em>,\u201d 85% of the debris from humans on coral reefs is plastic<\/strong>, with fishing items accounting for most of the debris.[28]<\/sup> Given the difficulties surveying coral reefs, especially deep reefs, the authors expect the actual amount of plastic debris on reefs to be much higher than current estimates.<\/p>\n\n\n\n

The study concluded that macro<\/em>plastics (plastic debris larger than 5 cm) are more common on deep coral reefs than shallow ones, contrary to intuition and a distressing finding about the reach of human impacts.[29]<\/sup> Restoring reefs and preventing further pollution is more difficult at deeper levels, and deeper reefs are currently less represented in policies seeking to protect coral reefs.[30]<\/sup><\/p>\n\n\n\n

Plastic pollution on coral reefs is a problem because it harms reef species in a variety of ways. Some species will mistake plastic for food<\/strong>, potentially thinking that plastic is even better than their food.[31]<\/sup> Plastic waste on coral reefs can promote coral disease \u2013 corals in contact with plastic have an 89% likelihood of disease, compared with only 4% for corals not polluted by plastic.[32]<\/sup> Diseased corals impact the reef organisms who rely on corals as habitats.<\/p>\n\n\n\n

Other factors such as an increase in ocean temperature and acidity (because of high and increasing levels of CO2<\/sub> in the atmosphere which is absorbed by the ocean), sea level rise, problematic fishing practices, and overfishing are placing further stress on corals and reef organisms.[33]<\/sup><\/p>\n\n\n\n

Keeping coral reefs healthy is important for more than preserving biodiversity because hundreds of millions of people across the globe rely on coral reefs for food.<\/strong>[34]<\/sup><\/strong><\/p>\n\n\n\n

Because of high amounts of plastic debris in the oceans, seabirds end up eating plastic or prey contaminated which then can cause harmful chemical accumulation and blockages in their digestive tracts.[35]<\/sup> As with corals, fishing gear poses a large threat to seabirds.[36]<\/sup><\/p>\n\n\n\n

Stage 5: Rewriting the Story with Plastic Policies & Individual Power<\/h3>\n\n\n\n

Given the widespread reach of plastic impacts, scientists and policymakers have recognized the need for reform of the plastic economy.[37]<\/sup><\/p>\n\n\n\n

In March 2022, the UN Environment Assembly approved a resolution aimed at ending plastic pollution by tasking a committee to draft an international legally binding treaty.[38]<\/sup> In May of this year, delegates continued to negotiate the treaty at the Intergovernmental Negotiating Committee in Paris, and the EU committed to further measurements in support of the treaty\u2019s goal to stop plastic pollution by 2040.[39]<\/sup> In several recent scientific papers, such as those published in Nature<\/em>, authors stressed the importance of considering new findings about plastic pollutions\u2019 breadth, patterns, and impacts \u201cas the world moves toward a global treaty to tackle plastic pollution\u201d (Pinheiro et al.).[40]<\/sup><\/p>\n\n\n\n

As countries work on the international treaty, we can also support the goal by decreasing our personal plastic consumption. <\/p>\n\n\n\n
