What You'll Learn
Plastic waste in oceans
Plastic pollution in oceans comes from various sources, including rivers, coastal waters, and human activities on land. Rivers act as conveyor belts, carrying plastic waste from inland areas to the sea. Once plastic waste reaches the ocean, it can be carried by ocean currents, such as gyres, spreading the pollution worldwide. The Great Pacific Garbage Patch, located halfway between Hawaii and California, is a stark example of the impact of ocean currents, containing an estimated 100 million kilograms of plastic.
The presence of plastic in the oceans has severe effects on marine life. Larger plastic debris, such as bottles, bags, and fishing nets, can entangle and suffocate marine animals, leading to injury and mortality. For example, endangered species like Hawaiian monk seals and Steller sea lions have suffered entanglement and injuries due to plastic debris. Additionally, microplastics, formed from the breakdown of plastic waste, are ingested by marine organisms, filling their stomachs and causing nutritional issues. Research indicates that over 1,500 species in marine environments ingest plastics, highlighting the widespread impact on aquatic life.
The impact of plastic waste in oceans extends beyond marine life, affecting ecosystems and human health as well. Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and impacting millions of people's livelihoods and food production. Furthermore, microplastics have been found in human organs, and the chemicals from plastic products can leach into tap water, potentially causing various health disorders.
Addressing plastic waste in oceans requires a multifaceted approach. Scientists and conservationists advocate for improved waste management systems, better product design, and a reduction in single-use plastic manufacturing. Local and global organizations are working to clean up existing plastic pollution and prevent further contamination. Additionally, international resolutions, such as the "End Plastic Pollution" initiative by the UNEA-5.2, aim to create legally binding instruments to tackle plastic pollution throughout its lifecycle.

Plastic's impact on human health
Plastic pollution is a pressing issue that poses a serious threat to human health. At every stage of its lifecycle, from production to disposal, plastic contaminates the environment and adversely affects human well-being. The pervasive nature of plastic means that humans are exposed to it through daily life products, food and water, and even the air they breathe.
One of the primary ways plastic harms human health is through the release of toxic chemicals. Over 170 fracking chemicals used in plastic production have known toxic effects on humans, including cancer, neurological issues, reproductive and developmental problems, and immune system impairment. These toxins can enter the body through ingestion, inhalation, or dermal exposure. Plastic particles have been found in human lung tissue, and microplastics have even been detected in human livers, kidneys, and placentas.
The manufacturing and improper disposal of plastic contribute to air pollution and respiratory issues for millions worldwide. Additionally, plastic waste often ends up in landfills, oceans, and other ecosystems, contaminating drinking water sources and leading to further ingestion of microplastics by humans and animals. This ingestion can result in the transfer of toxic chemicals to humans through the food chain.
The impact of plastic pollution is particularly concerning for future generations. Studies have shown that exposure to plastics increases the risk of birth complications, impaired lung growth, and childhood cancer. The adverse effects are especially acute for children in the womb and young ones, with increased risks of prematurity, stillbirth, and birth defects of the reproductive organs.
Furthermore, plastic pollution contributes to climate change, warming temperatures, and extreme weather events, which have numerous associated health risks. The complex and intersecting health impacts of plastic pollution underscore the urgent need for a global approach to reduce plastic production, use, and disposal.

Plastic's impact on wildlife
Plastic pollution has a detrimental impact on wildlife, affecting all life, from microscopic animals to large predators. It is estimated that about 11 million tonnes of land-based plastic waste enter the ocean each year, with over 1500 species in marine and terrestrial environments known to ingest plastics. This plastic ingestion can block digestive tracts, pierce internal organs, and cause intestinal injuries, leading to internal bleeding and even death. For example, in 2018, a wild elephant in India died from ingesting plastic, resulting in blocked intestines and subsequent organ failure.
Plastic debris does not decompose but breaks down into microplastics, tiny plastic particles less than five millimetres long. These microplastics can pass through animals' digestive systems, leading to liver and cell damage and disrupting reproductive systems. They have been found in hundreds of species, including sea turtles, seabirds, marine mammals, and even in human livers and placentas. Scientists have also found microplastics in tap water, which may cause health issues such as developmental, reproductive, neurological, and immune disorders.
Additionally, wildlife can become entangled in plastic waste, trapping and immobilising them, making them vulnerable to starvation, dehydration, and predation. It can also cause physical injuries, such as deep cuts and, in some cases, limb loss. Birds are particularly affected, as plastic impedes their ability to fly and hunt effectively.
The impact of plastic pollution on wildlife is not limited to the oceans. Land-based mammals, including elephants, hyenas, zebras, tigers, camels, and cattle, have also suffered the unintended consequences of plastic waste ingestion. Furthermore, plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting the livelihoods and well-being of millions of people.
To address this issue, many scientists and conservationists advocate for improved waste management systems, better product design, reduced manufacturing of single-use plastics, and increased recycling. These measures aim to prevent plastics from entering waterways and oceans, protecting wildlife and preserving the health of ecosystems and the planet.

Plastic's contribution to climate change
Plastic is a significant contributor to climate change. As plastic is derived from fossil fuels, its production, use, and disposal are all linked with carbon emissions and greenhouse gases, which are responsible for global warming. The extraction and transport of fossil fuels, as well as the manufacturing and disposal of plastics, all contribute to these emissions. With the global economy moving towards renewable energy sources, the fossil fuel industry is increasingly relying on the growing demand for plastic to maintain its profits.
A study by the U.S. federal government found that the plastic industry is a major driver of climate change. It is estimated that by 2050, plastic production could account for between 21% and 31% of the global carbon emission budget required to limit the increase in global temperatures to 1.5 degrees Celsius. Currently, the industry emits four times more greenhouse gases than the airline industry, or the equivalent of around 600 coal-fired power plants. The production of plastic is also expected to become the largest driver of global oil demand growth from now until 2030, and nearly half the growth to 2050.
The impact of plastic on climate change is felt at every stage of its lifecycle. During the extraction of fossil fuels, large areas of land are cleared, releasing carbon dioxide into the atmosphere. The refining and manufacture of plastics are carbon-intensive activities, emitting CO2 and other greenhouse gases. Even after disposal, plastic does not decompose but breaks up into microplastics, which are found everywhere on Earth, including in the air, water, and food we consume. These microplastics have been shown to release greenhouse gases as they break down, and they also pose a threat to human and animal health.
To mitigate the impact of plastic on climate change, it is essential to reduce plastic production and transition away from fossil fuels. Recycling can also help, as recycled plastic reduces greenhouse gas emissions by about 42% compared to creating plastic with new materials. However, the benefits of recycling are limited, as only 9% of plastic is successfully recycled globally, and it can usually only be recycled once or twice before becoming waste. Therefore, the best options are to reduce, reuse, and choose products with reusable packaging.

Improved Waste Management Systems: Implementing better waste collection and disposal systems is essential. This includes providing access to controlled disposal services for solid waste and ensuring proper recycling, incineration, or landfill methods. The Basel Convention offers guidance on the environmentally sound management of plastic waste, aiming to regulate the transboundary movement of hazardous wastes.
Reducing Single-Use Plastics: Single-use plastics, such as plastic bags and food wrappers, account for a significant portion of plastic waste. Reducing the production and consumption of these items can significantly decrease plastic pollution. Governments and organizations are taking steps to limit or ban single-use plastic items, with some success.
Recycling and Reusing Plastics: Recycling is a crucial aspect of plastic waste management. However, the recycling rate of plastic waste is currently low, at only 9%. Encouraging and facilitating the recycling and reuse of plastic materials can help reduce the amount of plastic waste ending up in landfills and the environment.
Better Product Design: Designing plastic products with sustainability in mind can help reduce plastic waste. This includes using biodegradable materials, minimizing the use of harmful additives, and creating products that are easily recyclable or reusable.
Awareness and Education: Educating communities about the importance of plastic waste management and providing information on proper plastic waste disposal and recycling practices can foster a culture of environmental responsibility.
International Cooperation: Plastic pollution is a global issue that transcends borders. International cooperation and agreements, such as the Basel Convention and the efforts led by the United Nations Environment Programme (UNEP), are essential to address plastic waste management on a larger scale.
By implementing these strategies and continuing to innovate, we can work towards reducing plastic pollution and mitigating its harmful effects on the environment and human health.
