What You'll Learn
Plastic pollution is a global problem
The first Earth Day took place on April 22, 1970, with about 20 million Americans participating in 12,000 events to raise awareness of environmental issues. While plastic pollution was not yet a widely recognized issue, air pollution, oil spills, and smog were already causing public concern.
Since then, plastic pollution has become a more prominent issue, with Earth Day organizations recognizing it as one of the most obvious and long-lasting environmental concerns. Plastic pollution has severe consequences for human health and the environment. As plastic breaks down into microplastics, it releases toxic chemicals into our food, water sources, and the air we breathe. It also accumulates toxic substances as it passes through the food chain, eventually reaching top predator species, including fish consumed by humans.
The environmental damage caused by plastic use in consumer goods was estimated at US$40 billion per year in 2016. Plastic pollution also alters habitats and natural processes, reducing ecosystems' ability to adapt to climate change and affecting millions of people's livelihoods, food production, and social well-being. Rivers are the main pathway for plastic to reach our oceans, with 90% of ocean plastic coming from just ten rivers in India, Africa, and China.
To address this global problem, urgent and decisive actions are required. Organizations like EARTHDAY.ORG are advocating for a phase-out of single-use plastics, an end to fast fashion's overproduction and overconsumption, and investments in innovative technologies to build a plastic-free world. It is crucial to raise public awareness, promote recycling, and implement policies to reduce plastic pollution and protect our planet's health and biodiversity.

Plastic waste leaks into aquatic ecosystems
The first Earth Day was celebrated on April 22, 1970, in the United States. It was created to bring environmental issues into the national conversation, with a focus on air pollution. However, plastic pollution has become an increasingly prominent issue in the decades since.
Plastic waste leaking into aquatic ecosystems is a significant environmental concern. Annually, 19-23 million tonnes of plastic waste enter oceans, rivers, and lakes, polluting and altering these ecosystems. This pollution has a detrimental impact on habitats and natural processes, reducing the ecosystems' ability to adapt to climate change and affecting the livelihoods, food production, and social well-being of millions of people.
Plastic waste enters aquatic ecosystems through various pathways, with rivers being the main route. Ninety percent of the plastic in the oceans is carried by ten rivers, all located in India, Africa, and China. The degradation of plastic into microplastics further exacerbates the issue, as these microscopic particles can pollute oceans, air, and ecosystems, even entering the human food chain.
The sources of microplastics in the oceans include primary microplastics, which account for 15-30% of plastic pollution in the oceans. Abrasion of synthetic textiles and tyres contributes the most, releasing microplastics at different life cycle stages. Additionally, the breakdown of plastics into microplastics releases toxic chemicals, which circulate in the air and enter our food and water sources.
The magnitude of the problem is evident, with only 9% of the world's plastic being recycled. The rest ends up in landfills or the environment, including our oceans. This has led to urgent calls for action, with initiatives such as MARPLASTICCs aiming to end plastic pollution in Eastern and Southern Africa and Asia.
To address plastic waste leakage into aquatic ecosystems, EarthDay.ORG has set several goals, including promoting public awareness, phasing out single-use plastics, addressing the impact of fast fashion, and investing in innovative technologies to build a plastic-free world.

Plastic pollution affects human health
The first Earth Day took place in 1970, and since then, plastic pollution has become a pressing issue. Plastic pollution is a global crisis that negatively impacts the environment, animals, and humans. While the health impacts of plastics are still a relatively new area of research, it is evident that plastics cause diseases, disabilities, and premature deaths at every stage of their life cycle.
Secondly, humans are exposed to toxic chemicals and microplastics through inhalation, ingestion, and direct skin contact. An average person may ingest approximately 5 grams of plastic every week. Microplastics have been detected in meat, milk, and even the blood of humans and farm animals. These tiny plastic particles can also enter our bodies through the air we breathe.
Additionally, the production and disposal of plastics contribute to air, water, and soil pollution. The petrochemical industry, which produces plastics, has a history of toxic emissions, spills, and explosions. Plastic waste in landfills releases toxic chemicals into the soil, further contaminating our environment and food sources.
The impact of plastic pollution on human health is interconnected with its effects on the environment and animals. Climate change, biodiversity loss, disruption of carbon dioxide absorption by marine organisms, and impacts on soil health have consequences for human health and well-being. Plastic pollution also reduces ecosystems' ability to adapt to climate change, directly affecting millions of people's livelihoods, food production, and social well-being.
To address the health risks posed by plastic pollution, urgent action is required. Reducing plastic production, use, and disposal worldwide is essential. A shift towards a circular economy and the development of innovative technologies to build a plastic-free world are crucial steps in mitigating the health impacts of plastic pollution.

Plastic pollution impacts marine life
The first Earth Day took place in 1970, and since then, plastic pollution has become a pressing issue. While plastic has many benefits, it has detrimental effects on the marine environment and human health.
Plastic pollution is deadly to marine life and has impacted at least 267 species worldwide, including sea turtles, seabirds, and marine mammals. Marine animals can mistake plastic for prey, leading to ingestion, which can cause internal injuries and slow, painful starvation. For example, sea turtles struggle to differentiate plastic from their prey, and whales accidentally gulp down balloons. Seabirds that feed on the ocean surface are especially prone to ingesting plastic debris, and adults inadvertently feed plastic to their chicks, affecting their growth and survival. A study found that approximately 98% of chicks sampled contained plastic, and the ingested amount is increasing over time.
Plastic pollution also causes entanglement, leading to loss of limbs and fatalities. Large marine mammals, such as blue whales, are highly vulnerable to entanglement in ghost fishing gear, which includes discarded fishing ropes, nets, and pots made from plastic. It is estimated that 300,000 whales, dolphins, and porpoises die annually from ghost gear entanglement. Additionally, plastic debris can trap and entangle various marine creatures, from small crabs to large whales, making them vulnerable to predators.
Microplastics, invisible to the naked eye, are easily consumed by marine wildlife. They can adsorb toxins, transferring them to the fatty tissues of the organisms that ingest them. As microplastics are a recent discovery, their long-term impacts on marine life are yet to be fully understood. However, research shows that marine life ingesting plastics coated with pollutants can absorb these toxins into their bodies. For example, fish caught during a 2008 Pacific Gyre voyage were found to have ingested plastic fragments, with 35% of the sampled fish containing plastic pieces.
Plastic pollution also contributes to the spread of invasive marine species and alters marine habitats and natural processes. It reduces ecosystems' ability to adapt to climate change, directly affecting millions of people's livelihoods, food production, and social well-being.
To address plastic pollution, it is crucial to focus on prevention and source reduction. This includes minimizing plastic leakage into the environment, reducing plastic toxicity, and promoting plastic reuse, repurposing, and recycling. Public education and policy changes are also essential to reducing plastic consumption and littering.

Plastic waste disposal and recycling
Plastic pollution has become a pressing global issue, with plastic waste adversely affecting the environment and human health. The first Earth Day took place in 1970, and while plastic pollution was not a significant concern at the time, the environmental movement of the 1970s played a pivotal role in shaping American recycling programs.
The 1970s witnessed the emergence of recycling norms, with Oregon enacting the first beverage container deposit law in 1971. However, it's important to note that recycling practices have evolved over time, and the recycling symbol and curbside programs we associate with recycling today gained prominence in the 1970s and 1980s. Despite these initiatives, the reality is that plastic recycling has faced significant challenges.
Oil and gas companies have a history of promoting recycling to sell more plastic, even though they were aware, as evidenced by industry documents from the 1970s, that large-scale plastic recycling was unlikely to be feasible. Recycling plastic is challenging due to the degradation of resin properties and the high costs of separating plastics. As a result, much of the plastic waste ends up in landfills or the environment, contributing to pollution.
To address plastic pollution, it is crucial to improve waste management strategies and reduce plastic production. Initiatives like EARTHDAY.ORG advocate for a phase-out of single-use plastics, a shift away from fast fashion, and investments in innovative technologies to build a plastic-free world. Additionally, reducing mismanaged plastic waste, particularly in low-to-middle-income countries, is essential to mitigating the environmental impact of plastic pollution.
While recycling is an important part of the solution, it alone cannot solve the plastic pollution crisis. A systemic transformation towards a circular economy is necessary, addressing the environmental, social, economic, and health risks associated with plastics.
