Plastic production has a detrimental impact on people and the environment. The global production of plastic is increasing, with more than 300 million tons of plastic produced annually, and half of this is single-use plastic. The process of plastic production involves the use of fossil fuels, which are extracted through mining and drilling operations, including the controversial technique of fracking. This extraction process can damage soil and land and increase the risk of natural disasters. Plastic production also contributes to air and water pollution, as toxic substances are released into the environment, threatening human health and ecosystems. Additionally, plastic waste, including microplastics, can contaminate ecosystems and the food chain, leading to potential health risks for humans and wildlife. To address these issues, there are efforts to reduce plastic waste, promote recycling, and advocate for stricter regulations on plastic plants.

What You'll Learn
Plastic production's health impact on people
Plastic production has a significant impact on human health, and the environment we live in. Plastic pollution is found everywhere, from the Antarctic tundra to tropical coral reefs, and the ocean air we breathe. The effects of plastic production on human health have significant monetary costs, estimated at $920 billion in the US alone for diseases and disabilities caused by plastic-associated chemicals.
The main health risks associated with plastic production are exposure to toxic chemicals, ingestion of microplastics, and inhalation of plastic particles. Humans are exposed to plastics through daily life products, plastic-based medical supplies, food, water, and airborne plastic pollution. The incineration of plastic waste disperses toxic chemicals into the air, contaminating water and soil, which is lethal to all who come into contact with it. Microplastics have been found in human organs, including the liver, kidneys, and placentas, and can cause inflammation, genotoxicity, oxidative stress, apoptosis, and necrosis. These issues are linked to an array of negative health outcomes, including cancer, cardiovascular disease, diabetes, and auto-immune conditions.
Vulnerable groups, including children, women, and marginalized communities, are particularly at risk of the adverse health effects of plastic production. Children in the womb and young children face increased risks of prematurity, stillbirth, birth defects, neurodevelopmental impairment, impaired lung growth, and childhood cancer.
The effects of plastic production on human health are long-lasting and pervasive, with plastic waste taking between 100 to 1,000 years to decompose. The growing rate of plastic production, over-reliance on single-use plastics, and ineffective waste management are contributing to a worsening pollution crisis, with potential global health and social implications.
To address the human health impacts of plastic production, a lifecycle approach is necessary to understand the full scope of plastic's toxic impacts. This includes reducing plastic production, use, and disposal, and implementing measures to combat plastic pollution and regulate the plastic industry.

Plastic's contribution to climate change
Plastic production's contribution to climate change is significant. As 99% of plastics are created from fossil fuel feedstocks, plastic production is closely linked to the petrochemical industry. Petrochemicals are expected to become the largest driver of global oil demand growth from now until 2030. The extraction, refining, and manufacture of plastics are all carbon-intensive activities. In 2015, CO2 and other GHG emissions from plastic production reached 1.96 Gt of CO2e, with a cost of $341 billion annually.
The impact of plastic production on climate change is felt at every stage of its life cycle. From extraction to disposal, plastic production contributes to greenhouse gas emissions. For example, the extraction of natural gas for plastic feedstocks in the United States emits an estimated 12.5 to 13.5 million metric tons of carbon dioxide equivalent annually. Additionally, land disturbance due to pipeline development for oil and gas extraction has led to the clearing of millions of acres of land, resulting in the release of carbon dioxide.
Plastics also contribute to climate change through the release of heat-trapping gases throughout their life cycle. As plastics break down in the environment, they emit greenhouse gases. This includes microplastics, which are ingested by plankton and have been found in the air we breathe and Earth's atmosphere, impacting the climate.
The presence of microplastics in the ocean is particularly concerning. The ocean has historically sequestered 30-50% of carbon dioxide emissions from human-related activities. However, with plankton consuming increasing amounts of microplastics, the ocean's ability to mitigate climate change may be compromised.

Plastic waste and pollution
Plastic production has had an immense impact on people and the environment, and the issue of plastic waste and pollution is a pressing global concern. Plastic waste is an ever-growing problem, with significant environmental, economic, and public health implications. The production, use, and disposal of plastic materials have led to a range of issues that affect people's lives and livelihoods.
Plastic pollution is pervasive and persistent. Once plastic is in the environment, it can take hundreds or even thousands of years to degrade. During this time, it can have harmful effects on ecosystems and wildlife. Plastic waste can accumulate and clog waterways, contributing to flooding and the spread of diseases. It can also find its way into the oceans, where it breaks down into microplastics, which are then ingested by marine life, leading to health issues and even death. These microplastics are then potentially entering the food chain, with unknown consequences for human health.
The impact of plastic waste is felt most acutely in developing nations and coastal communities. Inadequate waste management systems in these areas often lead to plastic waste being dumped or burned, causing air and water pollution, and creating health hazards for local populations. The proliferation of plastic waste also affects tourism and fisheries, damaging local economies.
The environmental impact of plastic production and waste is significant. The process of producing plastic often involves the release of toxic chemicals and greenhouse gases, contributing to climate change and air pollution. Furthermore, as plastic degrades, it can release toxic chemicals, further contaminating soil and water sources. This pollution can have far-reaching consequences for human health, including respiratory issues and increased cancer risk.
Addressing plastic waste and pollution requires a multifaceted approach. Improved waste management systems, including recycling and proper disposal methods, are crucial. Educating communities about the impacts of plastic waste and promoting alternatives, such as reusable products and biodegradable materials, can also help mitigate the problem. Additionally, policy interventions, such as bans or taxes on single-use plastics, can provide incentives for more sustainable practices and products.
Overall, the impact of plastic waste and pollution on people and communities is profound and far-reaching. It affects the environment, human health, and local economies. Addressing this global issue requires urgent action from individuals, industries, and governments alike, working together to reduce, reuse, and recycle plastics more effectively and sustainably.

How plastic harms marine life
Plastic harms marine life in a multitude of ways. It is estimated that marine plastics contribute to the death of over 100,000 marine mammals annually, with plastic affecting marine species in various ways, from entanglement and injury to ingestion and toxic contamination.
Firstly, large items of plastic can capture and entangle marine mammals and fish, preventing them from escaping and leading to starvation, injury, and increased vulnerability to predators. Discarded fishing nets can also smother and break coral reefs, hindering their healthy growth. Large marine mammals, such as whales, are particularly susceptible to entanglement in ghost fishing gear, including ropes, nets, and pots made from plastic. This entanglement can be fatal, with an estimated 300,000 whales, dolphins, and porpoises dying each year from becoming entangled in ghost gear.
Secondly, smaller plastic fragments can float on the water surface, being mistaken for food by seabirds and other marine species, leading to suffocation, starvation, and toxic contamination. Sea turtles, for instance, may ingest plastic bags, causing a feeling of fullness that eventually leads to starvation. A study found that sea turtles that ingest just 14 pieces of plastic have an increased risk of death. Similarly, plastic waste in the ocean can encourage the growth of pathogens. A recent study concluded that corals in contact with plastic have an 89% chance of contracting diseases, compared to only a 4% likelihood for corals that are plastic-free.
Additionally, microplastics, which are invisible to the naked eye, can be easily consumed by wildlife. They have the ability to adsorb toxins, which then transfer to the fatty tissues of the organisms that ingest them. These microplastics can accumulate in the bodies of marine organisms, causing punctured organs or intestinal blockages.
Furthermore, plastic waste in the ocean can transport invasive marine species and pollutants through ocean currents. Marine life that ingests plastic coated with pollutants can absorb these toxins into their bodies. Research has shown that fish are ingesting plastic fragments, with 35% of the fish caught during a 2008 Pacific Gyre voyage found to have ingested plastic pieces.
The impact of plastic on marine life is far-reaching and devastating, threatening the health and survival of countless species. Addressing this issue requires a combination of individual action, public education, policy changes, and a shift towards more sustainable alternatives to single-use plastics.

The durability of plastic and its environmental impact
Plastic is a durable material, with a lifespan far outpacing that of other commonly used substances. Unfortunately, this durability has a significant environmental impact. Plastic does not decompose; instead, it breaks up into smaller pieces called microplastics, which are now found practically everywhere on Earth. These microplastics pose a threat to wildlife, causing punctured organs or intestinal blockages if ingested. They also enter the human body, with potential health consequences including hormonal imbalances, reproductive issues, and cancer.
The production of plastic is a significant contributor to climate change. The extraction and conversion of fossil fuels into plastic emit vast amounts of greenhouse gases, with the Organisation for Economic Co-operation and Development estimating that in 2019, plastic products were responsible for 3.4% of global greenhouse gas emissions, and 90% of these emissions came from creating new plastic products. The removal of land for oil extraction and pipeline construction has also released over 1.6 billion metric tons of carbon dioxide into the atmosphere.
The durability of plastic means that discarded items remain in the environment for generations, causing long-term issues such as littering, leaching of toxic components, and the contamination of ecosystems and food chains. In the marine environment, plastic pollution puts species at risk of ingestion, suffocation, or entanglement, with over 1,500 species known to ingest plastic. Land-based sources account for 80% of this marine litter, with plastic making up approximately 85% of it.
The impact of plastic pollution is felt by communities worldwide, with developed countries sending their plastic waste to developing nations for processing. These communities can become overwhelmed, leading to plastic waste piling up and causing health and environmental issues. The air pollution from plastic production facilities can also contribute to health problems in neighbouring communities, including asthma, lung cancer, brain and organ damage, and cardiovascular diseases.
Addressing the environmental impact of plastic's durability requires a multifaceted approach. Reducing single-use plastic consumption, improving waste management practices, advocating for stricter regulations on plastic plants, and supporting legislation that curbs plastic use are all essential steps towards mitigating the issue. Individuals can make a difference by adopting reusable alternatives, avoiding overly packaged items, repurposing old containers, and supporting companies committed to reducing plastic waste.
