The Daily Plastic Pollution Crisis: Understanding The Devastating Impact

Plastic pollution is one of the most pressing issues facing the planet today. Plastic is a synthetic, organic polymer made from fossil fuels, and its consumption has continued to rise, with an annual production of 460 million tonnes in 2019. The world creates around 57 million tons of plastic pollution every year, with plastic waste ending up everywhere from the deepest oceans to the highest mountaintops. Plastic pollution has severe environmental, health, and economic impacts. It affects biodiversity, food and water safety, burdens economic activities, and contributes to climate change. While global efforts to tackle plastic pollution are underway, improving waste management strategies and reducing plastic consumption are crucial to address this problem effectively.

Plastic pollution in the ocean

The majority of plastic pollution in the ocean is caused by littering of disposable plastic items such as food wrappings, plastic bags, bottles, and other single-use products. These items are not properly disposed of and eventually find their way into waterways and the ocean. It is estimated that around 50% of plastic is used just once and thrown away. In addition, about 20% of ocean plastic pollution comes from industrial fishing, and a significant portion comes from improper manufacturing processes.

The impact of plastic pollution on marine life is devastating. Thousands of seabirds, sea turtles, seals, and other marine mammals die each year due to ingesting plastic or becoming entangled in it. Plastic ingestion can cause starvation, internal injuries, and infections in these animals. According to research, 17% of the species affected by plastic pollution are on the International Union for Conservation of Nature Red List of Threatened Species. Additionally, microplastics have permeated the entire ocean, from the food chain to floating plastic bottles on the surface.

The economic costs of plastic pollution in the ocean are also substantial, estimated to be between $6-19 billion USD annually. These costs include impacts on tourism, fisheries, aquaculture, and cleanup efforts. Furthermore, the climate crisis is exacerbated by plastic production and incineration, which releases carbon dioxide and methane into the atmosphere, contributing to global warming.

To address this pressing issue, improving waste management strategies and reducing plastic production are crucial. While recycling is important, only about 10% of plastic is currently being recycled, with the rest incinerated or ending up in the oceans. Domestic policies and foreign investments in waste management infrastructure can play a significant role in tackling this global issue.

Plastic waste in landfills

The world produces around 350 million tonnes of plastic waste each year, with half of this waste going straight to landfills. The disposal of plastic waste in landfills poses significant environmental and health risks. Plastic is hard to degrade, so it persists in the environment for decades. If stranded in a landfill, plastic waste will likely remain there indefinitely, but only if the landfill is properly constructed and managed. However, because plastic does not degrade, landfills quickly fill up, requiring new space to accommodate additional waste.

In many countries, waste landfilling is not properly conducted, and plastic waste can gradually disperse into the environment, leading to increased pollution of land and water. The degradation of plastic waste in landfills can release harmful volatile organic compounds (VOCs) through oxidative photodegradation. These toxic substances pose risks to both the environment and human health. Additionally, the formation and spread of microplastics from landfills are significant concerns. As plastic waste degrades, it breaks down into smaller particles, including microplastics, which can be transported by air and leachate into surrounding environments.

Microplastics can also enter the environment indirectly through the fragmentation and degradation of larger plastics. Primary sources of microplastics emissions include plastic pellets from industry, washing machines, microbeads from personal care products, wastewater treatment plants, rubber roads, artificial turf, and tire wear. Emissions from wastewater treatment plants are considered a major contributor to microplastics pollution.

To address the issue of plastic waste in landfills, improving waste management strategies is crucial. While microbial degradation presents a promising alternative, there is an urgent need for enhanced waste management practices and policies to mitigate the harmful effects of plastic pollution. The best option is to limit plastic use through substitution or reuse, followed by separate collection and recycling. When properly managed, landfills can sequester fossil carbon in plastic, preventing it from harming the environment.

Plastic pollution in rivers and lakes

Plastic pollution is a critical global issue, with an estimated 8 million metric tons ending up in the oceans annually. While the oceans bear the brunt of this pollution, rivers and lakes are also significantly affected. Rivers are a major pathway for plastic waste to reach the oceans, and they are themselves polluted by plastic debris.

The production of plastic has increased dramatically over the past few decades, with the world now producing around 350 million tonnes of plastic waste each year. Only 9% of this waste is recycled, while half goes to landfills, and a fifth is mismanaged, often ending up in natural water bodies. Plastic is lightweight and easily transported by wind and water, making it a pervasive pollutant.

A recent study found that just 10 river systems, eight of them in Asia, carry between 88% and 99% of the river-borne plastic that ends up in the ocean. These include the Yangtze, the Indus, the Ganges, the Yellow River, the Hai He, the Pearl, the Amur, and the Mekong. The other two are the Nile and the Niger in Africa. The Yangtze alone dumps up to 1.5 million metric tons of plastic into the Yellow Sea.

Rivers in other parts of the world also contribute to plastic pollution. In the eastern United States, the Hudson River carries 300 million clothing fibers, half of them plastic, into the Atlantic Ocean daily. The Thames River in the UK has also been affected, with volunteers regularly cleaning up plastic bags and bottles from its shores. Wet wipes are another significant source of plastic pollution in the Thames, often flushed down toilets and discharged into the river during heavy rainfall.

Plastic pollution in the environment

Plastic pollution is one of the most pressing issues facing the planet today. It is a global crisis that affects all ecosystems, from the tallest mountains to the deepest ocean trenches, and has severe consequences for human health, wildlife, and the economy.

The world produces a staggering amount of plastic waste each year, with estimates ranging from 350 to 460 million metric tons. This waste comes from nearly all consumer and industrial activities, including construction, vehicles, electronics, and agriculture. The production and consumption of plastic have skyrocketed in recent decades, with the global production of plastic doubling since the turn of the century. This surge in plastic usage has resulted in a corresponding increase in plastic pollution.

A significant portion of this plastic waste ends up in the environment due to improper disposal and mismanagement. Mismanaged plastic waste is primarily disposed of at illegal dumpsites or burned in open pits, releasing harmful pollutants into the atmosphere. It is estimated that more than 100 million tons of plastic waste have accumulated in rivers and lakes, with an additional 30 million tons in the oceans between 1970 and 2019. These massive amounts of plastic pollution in waterways have devastating impacts on marine life and ecosystems.

The breakdown of plastic waste into microplastics and nanoplastics exacerbates the problem. Microplastics, smaller than 5 mm in size, are shed from products like synthetic textiles and tyres through abrasion. Even more concerning are nanoplastics, which are smaller than 100 nm and can cross cell membrane walls, entering living organisms. These tiny plastic particles have been detected in human blood, placentas, and food and drinks, including tap water, beer, and salt. The presence of nanoplastics in our food and water supply poses potential health risks, as several chemicals used in plastic production are known to be carcinogenic and can cause various disorders.

To address the plastic pollution crisis, a two-pronged approach is necessary. Firstly, improving waste management strategies is crucial. This includes implementing better recycling systems, properly disposing of plastic waste, and reducing the amount of plastic used in the first place. Secondly, a global plastics treaty is essential to tackle the transboundary nature of plastic pollution and its impact on biodiversity loss. Collective action on a global scale is required to address this pressing environmental issue effectively.

Global efforts to reduce plastic pollution

The world produces around 350 million tonnes of plastic waste each year, with estimates suggesting that between 1 and 2 million tonnes of plastic end up in our oceans annually. The issue of plastic pollution is a pressing one, and various global efforts are being made to tackle this problem.

One key approach is to improve waste management strategies, especially in low-to-middle-income countries, where most ocean plastics originate due to a lack of proper waste management systems. Domestic policies and foreign investments in waste management infrastructure can play a significant role in addressing this issue.

Several countries have taken decisive action to reduce single-use plastic products. For instance, Bangladesh was one of the first countries to ban plastic bags in 2002, and 76 other countries have since followed suit. Additionally, 32 countries have implemented taxes or other restrictions on the production and sale of plastic bags. In 2019, Guatemala banned single-use plastics, giving the public a two-year deadline to transition to alternatives. India, the second most populated country globally, has also struggled with plastic pollution due to inadequate waste management. To address this, they passed a comprehensive ban on single-use plastic products, outlawing their production, distribution, and use.

The tourism industry has also been a significant contributor to plastic waste, with many single-use products associated with travel and tourism. To address this, the Global Tourism Plastics Initiative was launched to ensure that businesses, governments, and stakeholders take action to reduce plastic pollution. The initiative aims to have concrete agreements and terms in place by 2025.

In addition to government and industry initiatives, individuals can also play a crucial role in reducing plastic pollution. Learning how to reduce plastic use, borrowing or reusing items instead of buying new ones, and recycling are all effective ways to minimise one's plastic footprint.
