Plastic is everywhere, from tea bags to grocery bags, and has become one of the most pressing environmental issues. Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or non-existent. The production of plastic generates heat-trapping gases at every stage of its life cycle, from refinement and cracking to disposal. Plastic is derived from fossil fuels, and the burning of these fuels releases toxic chemicals into the atmosphere, impacting the climate and human health. Plastic waste is often sent to landfills, leaked into the environment, or incinerated, with incineration facilities disproportionately built near communities of colour and low-income populations. Single-use plastics, designed for convenience and one-time use, account for 40% of plastic produced annually and contribute significantly to the plastic waste crisis. With global plastic production increasing drastically, it is essential to understand the harmful effects of plastic on the environment and human health and to take steps towards reducing plastic consumption and promoting sustainable alternatives.

What You'll Learn
Plastic is made from fossil fuels
The history of plastic's connection to fossil fuels is relatively recent. The first fully synthetic plastic, called Bakelite, was invented in 1907 by Belgian chemist Leo Baekeland. Bakelite was produced by synthesizing coal tar and wood alcohol. However, it was during World War II that the US Military began experimenting with more universal uses of plastic, and chemists began working with fossil fuels to create plastics. After the war, commercial plastic demand increased, and manufacturers relied on fossil fuels to meet this demand, creating cheaper plastic products.
The production of plastic generates toxic emissions and hazardous working conditions. Manufacturing plastic resin creates more toxic emissions than manufacturing glass. For example, producing a 16 oz PET bottle generates over 100 times the toxic emissions to air and water than making the same-sized glass bottle. In addition, serious accidents have occurred in plastic production, including explosions, chemical fires, spills, and toxic vapors, resulting in deaths, injuries, evacuations, and property damage.
The use of plastic has also led to a throw-away culture, with single-use plastics accounting for 40% of the plastic produced annually. These products have a short lifespan but can persist in the environment for hundreds of years, ending up in landfills, oceans, and the stomachs of marine life. Plastic pollution has become one of the most pressing environmental issues, with rapidly increasing production overwhelming the world's ability to manage it.
Furthermore, plastic contributes to climate change throughout its life cycle. From fossil fuel extraction to plastic manufacturing and waste disposal, greenhouse gas emissions are associated with every stage. The CIEL report projects that if plastic production and incineration continue to increase, greenhouse gas emissions will rise to 49 million metric tons by 2030 and 91 million metric tons by 2050.

Plastic manufacturing is toxic
The toxic chemicals released during plastic manufacturing contribute to air pollution and are hazardous to workers. Additionally, plastic "nurdles" or pellets, escape from facilities and enter waterways and oceans, endangering marine life and ecosystems. The refining process aims to minimize waste, but point-source air emissions remain high due to the challenges of handling large flows of pressurized gases.
The plastic manufacturing process also contributes to climate change. Plastics generate heat-trapping gases at every stage of their life cycle, from production to disposal. The burning of fossil fuels during production releases greenhouse gases, and incineration of plastic waste further increases greenhouse gas emissions. The placement of landfills for plastic waste can also lead to environmental injustices, as they are often located near communities of color and low-income populations.
The toxic cycle of plastic pollution is fueled by the continuous increase in plastic production. Manufacturers produce more plastic each year, leading to a throw-away culture with single-use plastics accounting for a significant portion of annual plastic production. These single-use plastics have short lifespans but can persist in the environment for hundreds of years, contributing to plastic pollution in oceans, rivers, and coastal waters.
The negative impacts of plastic manufacturing extend beyond the environment. Plastic packaging contains additives that can migrate into food, posing potential health risks to consumers. Certain chemical additives in plastics, such as lead, cadmium, and mercury, are directly toxic, while others, like diethyl hexylphosphate (DEHP), are carcinogenic. These problem chemicals are used to enhance the performance properties of plastic products but have detrimental effects on the environment and human health.

Plastic waste is everywhere
The ubiquitous presence of plastic waste is an undeniable and pressing global issue. Plastic has infiltrated almost every corner of our planet, from the highest mountains to the deepest oceans, and its impact on the environment is profound and far-reaching. Plastic production has skyrocketed since its large-scale introduction in the 1950s, and so has plastic waste. The production and use of plastics have had a significant impact on the environment, and the issue of plastic waste is a critical one.
On land, plastic waste is just as pervasive. It litters our streets, parks, and natural habitats, breaking down into microplastics that contaminate our soil and water sources. Wildlife on land is also affected, often ingesting plastic or becoming entangled in it. Even in remote and seemingly pristine locations, plastic waste can be found. For example, Mount Everest, the world's highest mountain, has significant plastic pollution due to the accumulation of waste left by climbers over the years.
Plastic waste also has a significant impact on human health. Microplastics, those tiny plastic particles that result from the breakdown of larger plastic items, can find their way into our food and water systems. These microscopic pieces of plastic can be ingested by humans, potentially leading to unknown health consequences as they accumulate in our bodies over time. Additionally, the chemicals used in plastic production, such as phthalates and bisphenol A (BPA), can leach out and contaminate food and water, leading to potential endocrine disruption and other health issues.
The ubiquity of plastic waste is a stark reminder of the need for urgent action. While plastic has brought many benefits to our lives, its improper management and disposal have led to a global crisis. To address this issue, a multifaceted approach is necessary. This includes improving waste management practices, promoting recycling and the development of biodegradable plastics, and, most importantly, reducing our reliance on single-use plastics.
The problem of plastic waste is a shared global responsibility. It calls for collaborative efforts from individuals, industries, and governments alike to reduce plastic consumption, improve waste management, and support innovative solutions for a more sustainable future. Only through collective action can we hope to stem the tide of plastic pollution and protect our planet for future generations.

Plastic harms wildlife
Secondly, the production and refining processes of plastic contribute to climate change, which indirectly affects wildlife. Plastic is derived from fossil fuels, and the burning of these fuels releases greenhouse gases, leading to global warming and climate change. According to the Center for International Environmental Law, the plastic sector's fossil fuel consumption is projected to increase, contributing to rising temperatures and altering habitats for numerous species.
Thirdly, the toxic additives used in plastic production can contaminate the environment and harm wildlife. These additives, such as lead, cadmium, mercury, and diethyl hexylphosphate (DEHP), can have direct toxic effects or act as carcinogens. When plastic products end up in landfills or are incinerated, these toxic additives can leach into the environment and impact the health of wildlife.
Finally, plastic pollution has a significant impact on aquatic ecosystems. Plastic waste flows into oceans from rivers, accumulating in coastal waters and then being transported by ocean currents worldwide. This plastic pollution disrupts marine life and ecosystems, with microplastics being ingested by marine organisms and larger plastics entangling or harming various species. The presence of plastic in the oceans affects the health and survival of marine wildlife, including endangered species, and can lead to population declines and ecological imbalances.
Overall, plastic poses a significant threat to wildlife through direct physical harm, climate change, toxic chemical contamination, and disruption of aquatic ecosystems. Addressing these issues requires a transition towards more sustainable materials, improved waste management practices, and a reduction in plastic consumption to minimize the harm caused to wildlife.

Plastic waste is difficult to dispose of
Plastic waste is extremely challenging to dispose of. Plastic is derived from fossil fuels, including natural gas and crude oil, and is designed to be strong and durable. This means that it does not easily decompose and can persist in the environment for hundreds of years, with some estimates suggesting plastic can take at least 400 years to break down.
The most common methods of dealing with plastic waste are landfilling and incineration, both of which have significant negative impacts on the environment and vulnerable communities. Landfills are often placed in locations that perpetuate environmental injustices, and the plastic waste buried in them can remain intact for long periods, especially when shielded from direct sunlight. Incineration of plastic waste releases heat-trapping gases and toxic emissions, contributing to climate change and air pollution. The facilities are disproportionately built near communities of colour and low-income populations, subjecting them to the negative health impacts of pollution.
Recycling is another option for plastic waste disposal, but it faces challenges. The recycling process can be costly, and the low commercial value of recycled plastics makes it rarely profitable without government subsidies. Additionally, the complexity of plastic resin codes and the presence of incompatible resins can hinder the effectiveness of recycling. While recycling is a step towards reducing plastic waste, it is not a comprehensive solution.
The pervasive nature of plastic waste, from the top of Mount Everest to the deepest oceans, underscores the urgency of addressing this issue. Plastic pollution affects both the developed and developing world, with garbage collection systems in the latter often inefficient or non-existent, leading to communities overwhelmed by plastic trash. The throw-away culture associated with single-use plastics exacerbates the problem, as these plastics account for 40% of the plastic produced annually, despite having lifespans of only a few hours in some cases.
The toxic cycle of plastic pollution, from production to disposal, demands a transition towards zero waste to mitigate its harmful effects on the environment and human health.

Frequently asked questions
Plastic is made from fossil fuels, and the process of refining these fuels releases countless toxic chemicals into the air. Plastic manufacturing also discharges harmful substances into the air, which can have severe health impacts.
Plastic pollution is most visible in developing Asian and African nations, where garbage collection systems are often inefficient or non-existent. Plastic waste is sent to landfills, leaked into the environment, or incinerated. Landfilling has a lower climate impact than incineration, but the placement of landfills can be associated with environmental injustices.
Plastic incineration has the largest climate impact of the three options. U.S. emissions from plastic incineration in 2015 were 5.9 million metric tons of carbon dioxide equivalent, and if plastic incineration increases as expected, emissions will increase to 91 million metric tons by 2050. Incineration facilities are disproportionately built near communities of colour and low-income populations.
Plastic trash in the ocean comes from land, carried by major rivers that pick up trash as they move downstream. Once caught in ocean currents, plastic can be transported worldwide. Plastic in the ocean puts marine life and ecosystems in jeopardy, with millions of animals killed by plastics every year.
