What You'll Learn
Plastic pollution is a global problem
The production and use of plastic have skyrocketed since the 1950s, and with it, the amount of plastic waste. Plastic waste is flowing into nature at an unprecedented rate, with more than a dump truck load entering our oceans every minute. This waste comes from a variety of sources, including urban and stormwater runoff, littering, industrial activities, tyre abrasion, construction, and agriculture. Rivers are a significant conduit, carrying trash from cities to the marine environment.
The durability and resistance to degradation that make plastics so useful also make them nearly impossible for nature to break down. Most plastic items never fully disappear; they only get smaller, breaking down into microplastics and nanoplastics that can be ingested by wildlife and end up in our food and water systems. It is estimated that there are between 15 trillion and 51 trillion microplastic particles in our oceans, with 8 million metric tons of plastic entering the ocean each year.
To address this crisis, a systemic transformation is needed, including a shift towards a circular economy with increased recycling, reuse, and refill systems. While individual behaviour changes are important, they are insufficient on their own. Strong policies and legislation are required to keep producers of plastic accountable, reduce plastic production, improve waste management, and phase out harmful products and chemicals. Large-scale corporate action and government initiatives are necessary levers for change, and organizations like WWF and the UNEP are advocating for this at a global level.

Plastic waste harms the environment and human health
Plastic waste is a pressing global issue that poses significant threats to both the environment and human health. The persistence of plastic waste in the environment and its potential toxicity make it a dangerous pollutant, with far-reaching consequences.
The production of plastic waste has increased dramatically over the years, with a significant rise in plastic waste generation since the 1990s. This has resulted in an estimated 300 million tonnes of plastic waste being produced annually, which is roughly equivalent to the weight of the entire human population. A staggering 8 million tonnes of this waste ends up in our oceans each year, transported by rivers from cities. The durability of plastics, which makes them so useful in various applications, also contributes to their persistence in the environment. Plastic waste can take anywhere from 100 to 1,000 years or more to decompose, depending on environmental conditions. During this slow decomposition process, plastic waste can fragment into smaller pieces, known as microplastics, which range in size from 5 millimeters to one nanometer. These microplastics are pervasive, found in every ecosystem on Earth, from the Antarctic tundra to tropical coral reefs.
The presence of microplastics in the environment poses a significant threat to marine life. Over 1,500 species in marine and terrestrial environments are known to ingest plastics, mistaking them for food. These tiny plastic particles enter the food chain and can ultimately end up on our dinner plates. Microplastics have been detected in a majority of the world's tap water, and research has also found them in human lung tissue, livers, kidneys, and placentas. This indicates that humans are inadvertently consuming and inhaling microplastics, which can have harmful effects on our health.
The toxic chemical additives and pollutants found in plastics pose additional risks to human health. These chemicals have been linked to causing cancer and endocrine disruption, leading to reproductive, growth, and cognitive impairments. Furthermore, microplastics can act as vessels for pathogens, increasing the spread of diseases. The health impacts of plastics are an emerging area of research, and the full extent of the dangers may not yet be fully understood.
The environmental impact of plastic waste is also concerning. Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change. This, in turn, affects millions of people's livelihoods, food production capabilities, and social well-being. Plastic waste also contributes to air, water, and soil pollution, further exacerbating the harm to both the environment and human health.
Addressing the plastic pollution crisis requires systemic transformation and a transition to a circular economy. This includes reducing plastic waste, improving recycling and reuse practices, and shifting to sustainable sources for plastics. Individual actions, such as reducing single-use plastic consumption and advocating for change, are important, but strong policies and government action are also necessary to drive holistic system change and hold producers of plastic accountable.

Plastic is not biodegradable and pollutes ecosystems
Plastic is a human-made material that has transformed our world, from making hospitals safer to improving the efficiency of our packages. However, it has no place in nature. Plastic is not biodegradable, and its presence in ecosystems is causing pollution and degradation.
The very properties that make plastics so useful, such as their durability and resistance to degradation, are the reasons why they are nearly impossible for nature to break down. Plastic does not biodegrade; instead, it breaks down into smaller and smaller pieces over thousands of years. These tiny plastic particles are then often swallowed by animals and fish, ending up in our food and water systems.
The issue of plastic pollution is a global one, with plastic waste flowing into nature at an alarming rate. Every day, the equivalent of more than a dump truck load of plastic is dumped into our oceans alone, polluting the air, water, and soil that both people and nature need to survive. This waste comes from rivers, which act as conduits of trash from cities to the marine environment. An estimated 20 million metric tons of plastic litter end up in the environment annually, with 8 million tons in the oceans alone.
The effects of this pollution are far-reaching. Plastic pollution alters habitats and natural processes, reducing ecosystems' ability to adapt to climate change. It impacts biodiversity, with plastic particles being ingested by animals and finding their way into our food and water systems. It also affects economies and human well-being, as natural ecosystems are key to both.
While biodegradable plastics are being developed, they are not a complete solution. These materials may not break down in the natural world, leading to the same consequences as their non-biodegradable counterparts. Additionally, they are currently expensive to produce. Thus, a systemic transformation is needed to address the plastic pollution crisis, with a shift towards a circular economy and sustainable practices.

Plastic production needs to be reduced
Plastic pollution is a pressing global issue that requires urgent attention. The production of plastic has increased exponentially since the 1950s, and with it, the amount of plastic waste has also surged. This waste is polluting our oceans, rivers, and ecosystems, causing irreversible damage to the environment and affecting the lives of millions. Therefore, it is imperative that we reduce plastic production to address this crisis.
Plastic is produced from chemicals derived from oil, natural gas, and coal, which are non-renewable resources. The production and use of plastic contribute significantly to environmental degradation. The process of extracting and refining these resources is energy-intensive and releases greenhouse gases, contributing to climate change. Additionally, plastic waste clogs sewers, providing breeding grounds for mosquitoes and pests, which increases the transmission of vector-borne diseases such as malaria.
The complex and diverse types of plastics being produced also pose a challenge for recycling. The vast array of plastic polymers makes it difficult to identify, sort, and recycle them effectively. This results in a staggering amount of plastic waste ending up in landfills and dumps, further contributing to environmental pollution. Therefore, simplifying the types of plastics produced and transitioning to easily recyclable materials is essential.
The shift towards single-use plastics has exacerbated the problem. More than 99% of plastics are designed for temporary use, meant to be discarded after a single use. This has led to a throwaway culture, with plastic waste accumulating at an alarming rate. Single-use plastics, such as plastic bags, straws, and disposable cups, have a significant environmental impact and contribute to the pollution of our oceans and ecosystems.
Reducing plastic production is crucial to mitigating the adverse effects of plastic pollution. By decreasing the output of plastic, we can reduce the amount of waste that ends up in our natural environment. This requires systemic transformation and a transition to a circular economy, where plastic materials are sourced sustainably, reused, and recycled effectively. Governments and corporations must work together to implement policies and incentives that promote sustainable practices and reduce the reliance on single-use plastics.
In conclusion, the need to reduce plastic production is evident. By addressing the root causes of plastic pollution and implementing systemic changes, we can work towards a future with drastically reduced plastic consumption and eliminate plastic pollution from our planet.

With only 9% of plastic waste ever recycled, it is clear that improved waste management and recycling practices are key to combating this global crisis.
The durability and resistance to degradation that make plastics so useful in various industries also contribute to their persistence in the environment. Plastic waste does not completely break down but instead fragments into smaller pieces, known as microplastics and nanoplastics, that can be ingested by animals and contaminate our food and water sources. Rivers are a significant pathway for plastic pollution, carrying trash from cities out to the oceans.
To address the plastic pollution crisis effectively, a systemic transformation is required. This includes reducing plastic production, phasing out harmful plastics, and adopting more sustainable practices. While recycling is important, it is not enough on its own to solve the problem. A circular economy approach is needed, focusing on reducing, reusing, and recycling plastic materials.
At the individual level, people can advocate for change, support organizations like WWF and Oceanic Society that are working to address plastic pollution, and make conscious choices to reduce their plastic consumption and properly dispose of plastic waste. However, individual efforts alone are insufficient, and legislative action is necessary to drive systemic change.
Governments and policymakers play a crucial role in implementing measures to reduce plastic waste, such as running public awareness campaigns, offering incentives for recycling, introducing levies or bans on certain plastic products, and holding plastic producers accountable for the waste they generate. Large-scale corporate action is also necessary, with major companies advocating for federal government policies that incentivize good behavior and support collaborative efforts to address plastic pollution. By combining improved waste management, increased recycling, and systemic change, we can make significant strides in tackling the pressing issue of plastic pollution.
