Littering's Impact: Understanding Pollution Caused By Carelessly Discarded Waste

Littering is the improper disposal of waste products, which can have significant environmental and public health consequences. It contributes to air, land, and ocean pollution, with an estimated 8 million tons of plastic waste entering our oceans annually. Littering affects wildlife, with over 1 million animal deaths yearly due to ingestion or entanglement in trash. It also degrades soil health and plant growth, blocks sunlight, and spreads diseases. Additionally, open-air burning of litter releases toxic emissions, causing respiratory issues and potentially serving as a base for acid rain.

How much pollution is caused by littering?

Cigarette butts are the most frequently littered item and are toxic to the environment

Cigarette butts are the most frequently littered item, with an estimated 9.7 billion discarded along roadways and waterways in the US alone. They are also the most abundant form of plastic waste in the world, with about 4.5 trillion individual butts polluting the global environment. This makes them a significant contributor to land and water pollution.

Cigarette butts are made of cellulose acetate, a man-made plastic material that can take up to 10 years to degrade fully. In the meantime, they leach hundreds of toxic chemicals, including nicotine, heavy metals, arsenic, and lead, into the surrounding environment. These toxins are harmful to both people and wildlife. For example, a laboratory study found that the chemicals leached from a single cigarette butt soaked in water for 24 hours were enough to kill 50% of the saltwater and freshwater fish exposed to it for 96 hours. Another study found that patterns of hydrocarbon levels in soil contaminated with cigarette butts were similar to those found in roadside waste, indicating that the chemicals had seeped out of the cigarette butts and into the soil.

The improper disposal of cigarette butts is a serious environmental issue. When thrown onto the street, out of a car window, or down a drain, they slowly release toxins into our natural water and soil systems. This is especially true for low-income communities of color, which have higher smoking rates and often face inequities in waste management services, leading to contaminated waterways. Furthermore, cigarette butts are often ingested by marine animals, causing serious health risks, including suffocation and increased mortality.

The problem of cigarette butt litter is not limited to traditional cigarettes. The rise in popularity of e-cigarettes has led to a new form of litter that contains plastic, electronic, and chemical waste. While e-cigarette waste cannot biodegrade, even under severe weather conditions, it eventually breaks down into microplastics and chemicals that pollute waterways and harm wildlife. The environmental impact of tobacco extends beyond littering, with tobacco farming contributing to global deforestation. Comprehensive approaches to waste management, tobacco use control, and mitigating the environmental impacts of tobacco are needed to address this issue effectively.

The US spends $11.5 billion annually to clean up litter

The US spends a staggering $11.5 billion annually to clean up litter, according to Keep America Beautiful. This figure is likely to increase due to the COVID-19 pandemic, which caused a surge in plastic waste. The pandemic's impact on trash output is significant, with a rise in plastic packaging, food containers, and PPE gloves and masks.

Littering is the improper disposal of waste products, and it has severe environmental and public health consequences. It contributes to air, land, and ocean pollution, with approximately 8 million tons of plastic waste entering our oceans annually. This plastic waste endangers marine life, with over 100,000 dolphins, fish, whales, and turtles dying from entanglement or ingestion of plastic litter each year.

The costs of cleaning up litter are not just financial. Heavily littered neighbourhoods experience more vandalism and crime, and litter can lower property values and reduce tourism. The presence of litter also affects people's mental health, with studies showing that even viewing photographs of littered beaches can cause stress in individuals.

Cigarettes are the most frequently littered item, with 4.5 trillion butts discarded annually along roadways and waterways. Cigarette butts contain over 4,000 cancer-causing chemicals, which leach into the soil and water, causing further environmental damage. The toxic litter from cigarettes amounts to 1.69 billion pounds each year.

The financial burden of cleaning up litter falls largely on businesses, which pay about 80% of the $11.5 billion annual cleanup bill. This cost is often passed on to employees and customers, creating a ripple effect throughout the economy.

Marine debris can lead to declining fish populations and damage boats

Marine debris is defined as "any persistent solid material that is manufactured or processed and directly or indirectly, intentionally or unintentionally, disposed of or abandoned into the marine environment or Great Lakes". It is one of the most pervasive global threats to the health of the world's coastal areas, oceans, and waterways. Marine debris can lead to declining fish populations and damage boats in several ways.

Firstly, marine debris can injure or kill marine life, including fish. Plastic ingestion leads to loss of nutrition, internal injury, intestinal blockage, starvation, and death in wildlife. Seabirds are especially vulnerable to plastic pollution, with a recent study finding plastic in 90% of seabirds. Marine debris can also cause entanglement in fish and other marine animals, leading to injury and death. Derelict fishing gear, such as nets, ropes, and lines, can wrap around marine life, including fish, and cause entanglement.

Secondly, marine debris can damage boats and interfere with navigational safety. Abandoned and derelict vessels can obstruct navigational channels, causing collisions and damage to other vessels. Large debris, such as derelict fishing gear, vessels, and appliances, can also crush and smother sensitive habitats, such as coral reefs. Marine debris can also create hazards for boaters, such as sharp objects or hazardous substances that can cause harm to people in the water.

Additionally, marine debris can cause economic loss to fishing and maritime industries. Derelict fishing gear can result in lost catch opportunities and economic losses for fishermen. Marine debris can also degrade the quality of life in coastal communities and threaten human health and safety. For example, there may be plastic in the seafood we eat, although the health risks associated with different plastics and chemicals are still unknown.

Overall, marine debris is a significant problem that can lead to declining fish populations and damage boats through a variety of direct and indirect impacts. It is important to address the issue of marine debris through proper waste management, litter prevention, and collaborative efforts to mitigate its environmental, economic, and public health consequences.

Plastic pollution is particularly harmful as it does not fully biodegrade

Plastic pollution is a pressing global issue, with plastic waste finding its way into our oceans, rivers, and lakes. The improper disposal of plastic products has severe environmental and public health consequences. Plastic pollution is particularly harmful as it does not fully biodegrade, persisting in the environment for hundreds of years.

Plastics are designed to be durable, but this durability becomes a problem when plastics are discarded. Plastic waste can take between 100 to 1,000 years or more to decompose, depending on environmental conditions. During this lengthy decomposition process, plastic waste fragments into smaller pieces, known as microplastics. These microplastics are spread by wind, water, and other natural forces, reaching even the most remote and pristine ecosystems on Earth. From the Antarctic tundra to tropical coral reefs, no ecosystem has been left untouched by microplastics.

The persistence of plastic pollution in the environment poses significant risks to both wildlife and human health. Marine species are at high risk of ingesting plastic, which can lead to starvation or suffocation. Nearly 2,100 species, including endangered ones, are known to be affected by plastics. Birds, fish, and other marine organisms often mistake microplastics for food, leading to the presence of plastic particles in their digestive systems. This issue is not limited to marine life, as nearly every species of seabird has been found to consume plastics.

The impact of plastic pollution on human health is also a growing concern. Microplastics have been detected in human blood, lungs, and feces, and their presence in tap water has been linked to potential developmental, reproductive, neurological, and immune disorders. Carcinogenic chemicals found in plastic products can leach into water sources, posing risks to human health. While the full extent of the harm caused by microplastics is still being studied, the widespread presence of plastics in the environment underscores the urgency of addressing this issue.

To summarize, plastic pollution is particularly harmful due to its persistence in the environment, leading to ecological damage, risks to wildlife, and potential adverse effects on human health. Addressing plastic pollution requires a combination of improved waste management practices, reduced plastic consumption, and the development of more sustainable alternatives to single-use plastics.

Land pollution due to littering is a huge problem in today's society

Littering contributes to land, air, and water pollution. It degrades the beauty of an area and has long-term effects on the health of our communities. For example, plastic waste can take decades or even centuries to decompose, all the while releasing toxic chemicals into the soil and water. This not only affects plant growth and soil health but also harms animals that ingest or become entangled in the litter. Researchers estimate that over one million animals die each year from ingesting or becoming trapped in litter, with plastic being the most common cause of death.

Cigarettes are the most frequently littered item, with 9.7 billion cigarette butts discarded along roadways and waterways. Since the COVID-19 pandemic, there has also been an increase in Personal Protective Equipment (PPE) litter, with 207 million gloves and masks estimated to be littering roadways and waterways. These items can block sunlight and prevent plants from photosynthesizing, causing a decline in plant biodiversity.

Furthermore, litter can be a breeding ground for bacteria and diseases, which can spread through direct and indirect contact. It can also contribute to air pollution when burned in the open air, releasing toxic emissions that cause respiratory issues and other health problems.

The problem of land pollution due to littering is a pressing issue that requires collective action to address. By properly disposing of waste and being mindful of the impact of our actions on the environment, we can work towards creating a cleaner and safer world for both humans and animals.
