The Impact Of Rubbish Pollution On Our Environment

Rubbish pollution is a pressing issue that has devastating effects on the environment. With over two billion metric tons of human-generated waste disposed of globally each year, the planet is struggling to cope with the sheer volume of rubbish. This waste ends up in landfills, oceans, rivers, and the soil, leading to air, land, and water pollution. The breakdown of waste releases harmful gases, such as methane and carbon dioxide, contributing to climate change. Improper waste disposal also poses risks to human health, with toxic chemicals and microparticles released into the environment. Additionally, rubbish pollution threatens wildlife, with animals ingesting or becoming entangled in litter, leading to deaths and extinctions. The impact of rubbish pollution extends to ecosystems, altering habitats and reducing their ability to adapt to a changing climate. Addressing rubbish pollution requires a systemic transformation, improved waste management, and a reduction in the use of single-use plastics.

Landfills and air pollution

Landfills are necessary for the proper disposal of solid waste, helping to keep communities clean and prevent disease transmission. However, they also contribute to air pollution and have a significant environmental and social impact. Landfills emit methane, a greenhouse gas with a warming potential over 80 times greater than carbon dioxide, making it a huge contributor to climate change. The release of methane is a result of the decomposition of organic mass in landfills. Landfills are also a source of other gases such as carbon dioxide, water vapour, and trace amounts of oxygen, nitrogen, hydrogen, and non-methane organic compounds. These gases can contribute to climate change and create smog if not controlled.

The impact of landfills on air pollution is significant, with the gases they emit causing adverse health effects. For example, short-term exposure to elevated levels of ammonia and hydrogen sulfide, which are also present in landfill gas, can cause coughing, irritation of the eyes, nose, and throat, headaches, nausea, and breathing difficulties. Additionally, methane is highly flammable and can form explosive mixtures with air if it concentrates in enclosed spaces with poor ventilation.

The movement of landfill gases into nearby buildings is another concern. Landfill gases can move through the soil and collect in indoor spaces, displacing oxygen and potentially causing health issues such as a faster heartbeat and deeper breathing due to reduced oxygen levels. This movement of gases is known as soil vapour intrusion and can occur through cracks in basement floors and walls, utility entry points, and floor drains.

To mitigate the impact of landfill gases, modern landfills employ gas collection systems to prevent the release of greenhouse gases into the atmosphere. These systems use perforated pipes to collect the gases and direct them vertically to the surface, where they can be vented, burned, filtered, or used for energy recovery. Older landfills and smaller dumps may not have such control measures, increasing the risk of gas migration into nearby buildings and the surrounding air.

While landfills play a crucial role in waste management, their contribution to air pollution and climate change is undeniable. It is essential to explore alternative waste management strategies, such as recycling and composting, to reduce our reliance on landfills and mitigate their impact on the environment and human health.

Oceans and water pollution

Our oceans are being polluted by rubbish, threatening marine life and ecosystems. The majority of ocean pollution comes from human activities along coastlines and far inland.

Sources of Ocean Pollution

The sources of ocean pollution can be divided into two categories: nonpoint source pollution and point source pollution. Nonpoint source pollution occurs as a result of runoff and can come from many sources such as septic tanks, vehicles, farms, livestock ranches, and timber harvest areas. Point source pollution comes from a single source, such as an oil or chemical spill, or discharge from faulty or damaged factories or water treatment systems.

Effects of Ocean Pollution

Ocean pollution has a detrimental impact on marine life and ecosystems. Animals can become entangled in or ingest plastic debris, leading to suffocation, starvation, and drowning. It is estimated that at least 800 species worldwide are affected by marine debris, and as much as 80% of that litter is plastic. Plastic waste can also encourage the growth of pathogens in the ocean. According to a recent study, scientists found that corals that come into contact with plastic have an 89% chance of contracting a disease, compared to a 4% likelihood for corals that are not exposed to plastic.

Addressing Ocean Pollution

Local, national, and international efforts are needed to address this environmental problem. Individuals can play a role by reducing their plastic consumption and properly disposing of or recycling waste. Additionally, supporting policies and businesses that prioritise reducing plastic production and promoting more environmentally friendly alternatives can help to combat ocean pollution.

Climate change

The climate impacts of rubbish pollution are becoming increasingly evident and harder to ignore. Poor waste management and the rubbish that ends up in landfills contribute to air pollution and climate change. Landfills are a significant source of greenhouse gas emissions, particularly methane and carbon dioxide, which are produced by the decomposition of waste. Methane is more than 80 times more potent than carbon dioxide as a climate pollutant in the short term and accounts for nearly half of the warming we have experienced so far.

The waste sector is one of the top three methane-emitting sectors, responsible for about 20% of human-caused methane emissions globally. Solid waste emissions from landfills and dumps make up the majority of methane emissions from the waste sector. Here, organic waste, including food waste, yard waste, paper, cardboard, and wood, decays slowly over decades, releasing methane and carbon dioxide. The amount of methane produced is influenced by the amount of organic material in the waste, with lower-income countries having a higher proportion of food and green waste.

The open burning of waste, common in many parts of the world, is a significant source of air pollution and contributes to climate change. Incinerating plastics releases a cocktail of poisonous chemicals, including black carbon, which has a global warming potential up to 5,000 times greater than carbon dioxide. Additionally, plastic pollution in the ocean also contributes to climate change. As plastics slowly break down, they release methane and ethylene, with the rate of gas release increasing as the plastic fragments into smaller pieces.

The effects of rubbish pollution on the climate are far-reaching and have severe consequences. The increase in greenhouse gas emissions from landfills and waste incineration contributes to global warming and the overall climate crisis. Improving waste management practices, reducing waste generation, and increasing recycling and reuse are crucial steps to mitigate the impact of rubbish pollution on the climate.

Human and wildlife health

Rubbish pollution poses a significant threat to both human and wildlife health. The effects of rubbish pollution on wildlife are extensive and far-reaching, impacting a wide range of animal species.

Impact on Wildlife

Littering, especially plastic waste, has severe consequences for animals. One of the most common issues is entanglement, where animals of all kinds can become trapped and injured by waste products, leading to severe injuries or death. This is particularly prevalent among marine wildlife, with hundreds of thousands of marine mammals, including dolphins, seals, and whales, dying each year from entanglement.

Ingesting litter is another significant problem for wildlife. Animals may mistake trash for food, such as sea turtles consuming plastic bags that resemble jellyfish. This ingestion of litter can cause internal organ damage, starvation, decreased mobility, and poisoning. According to a 2016 United Nations (UN) report, nearly 50% of cetacean and seabird species have ingested litter.

Litter can also alter animal behaviour and reproduction rates. For example, white storks in Portugal have abandoned migration to live near landfills, leading to soaring population numbers, despite the potential consumption of plastic particles and other waste.

Impact on Humans

Rubbish pollution also has direct and indirect impacts on human health. Landfills, where rubbish ends up if not reduced, reused, or recycled, contribute to air pollution through the release of fumes and gases from decomposing waste. These fumes contain harmful substances like methane and carbon dioxide, which are known contributors to climate change.

Additionally, over 1,000 chemicals used in plastic products are classified as endocrine-disrupting and carcinogenic. These chemicals have been linked to various health issues in humans, including cancer, infertility, Alzheimer's, miscarriage, and developmental problems.

Furthermore, improper waste disposal can lead to water and soil contamination, affecting human health. For instance, agricultural waste containing pesticides and chemicals can contaminate soil and water sources, leading to potential health risks for humans who consume contaminated water or food.

Land and sea animal death

Plastic pollution is a pressing issue that poses a significant threat to both land and sea animals. It is estimated that plastic pollution contributes to the death of over 100,000 marine mammals annually, with 81 out of 123 marine mammal species known to have ingested plastic or become entangled in it. This issue is not limited to the oceans, as plastic pollution also affects freshwater ecosystems, including rivers, lakes, and streams.

One of the primary ways plastic pollution harms sea animals is through ingestion. Animals mistake plastic for food, leading to fatal blockages in their airways or stomachs. The ingested plastic may also release toxic chemicals, causing long-term health issues and even death. For example, a sperm whale stranded on a Spanish beach died due to inflammation caused by consuming nearly 30 kilograms of plastic. This problem is not limited to marine mammals, as sea birds and fish are also affected. It is estimated that plastic pollution kills one million sea birds and 100,000 sea fish annually.

Another way plastic pollution harms sea life is through entanglement. Abandoned fishing gear, such as nets and ropes, can trap marine animals, hindering their movement and causing drowning or severe injuries. Even if the entangled animal survives, the plastic can cut deep into their skin, leading to life-threatening infections. This issue affects a wide range of species, from large whales to small crabs and dolphins.

Plastic pollution also disrupts habitats, making it challenging for some species to live and breed naturally, leading to population depletion. Additionally, plastic waste can smother aquatic plants and corals, hindering their growth and damaging delicate coastal ecosystems.

The impact of plastic pollution on land animals is equally concerning. As plastic takes hundreds or even thousands of years to degrade, it persists in the environment and can be ingested by land animals, causing health issues and even death. Recent studies have detected microplastics in various land animal species, indicating the widespread reach of plastic pollution.

To address this issue, it is essential to reduce plastic waste, improve waste management practices, and increase public awareness about the dangers of plastic pollution to both land and sea animals. By making a collective effort to reduce, reuse, and recycle plastic, we can help protect the diverse range of species affected by this global issue.
