Plastic kills biodiversity and life chains

The Silent Threat of Plastic

Plastic — once hailed as a miracle of modern life — has become one of the greatest environmental threats of our age. From production to disposal, it damages ecosystems, harms biodiversity, and endangers human health. Global plastic production now exceeds 400 million tonnes annually, yet less than 10% is recycled. The remainder chokes oceans, contaminates soil, and poisons the air we breathe. The time to act is now.

From Creation to Catastrophe

The Lifecycle of Plastic

Every stage of plastic’s existence — extraction, manufacturing, distribution, and disposal — inflicts damage. Producing one tonne of plastic emits around six tonnes of CO₂. Additives like phthalates and bisphenols leak toxins into our bodies and ecosystems. Meanwhile, over eight million tonnes of plastic enter our oceans each year, suffocating marine life and disrupting food chains.

Once in the environment, plastics persist for centuries. As they break down, they release microplastics into the air, water, and soil — now found in human blood, lungs, and placentas. Plastic pollution isn’t just an environmental crisis; it’s a human health emergency.

The Lifecycle of Plastic: A Cycle of Destruction

Extraction and Production

Plastic begins its life as crude oil or natural gas, extracted through drilling and fracking processes that severely impact ecosystems. These extraction activities disturb local habitats, contribute to deforestation, and threaten wildlife. Moreover, the refining of fossil fuels into plastic releases toxic substances into the air and water, exposing nearby communities to significant health risks such as respiratory diseases and cancer. The Center for International Environmental Law highlights that for every ton of plastic produced, approximately six tons of carbon dioxide are released into the atmosphere, exacerbating global warming. This foundational step in the lifecycle of plastic sets the stage for a cascading series of environmental harms.

Manufacturing and Distribution

Once the raw materials are refined, they are transformed into plastic products in energy-intensive factories. During manufacturing, harmful chemicals such as phthalates and bisphenols are often added to plastics to enhance their durability or flexibility. These additives are not only harmful to human health but also contribute to environmental contamination. As these products are distributed globally, the transportation process adds another layer of carbon emissions, further burdening the planet. The packaging industry, which accounts for 40% of all plastic produced annually, is a primary driver of this environmental strain. Our World in Data reports that this overwhelming reliance on plastic packaging underscores the systemic inefficiencies and unsustainable practices embedded in global supply chains.

Disposal and Environmental Contamination

The end-of-life phase for plastics is equally concerning. Despite widespread recycling campaigns, only 9% of all plastic ever produced has been recycled. The rest ends up in landfills, incinerators, or the natural environment, where it persists for centuries. In landfills, plastics release methane, a potent greenhouse gas, as they slowly degrade. When incinerated, they release toxic fumes that contribute to air pollution and climate change. Worse still, an estimated eight million metric tons of plastic enter the oceans every year, wreaking havoc on marine ecosystems. The UN Environment Programme reports that plastic pollution kills over 100,000 marine mammals and one million seabirds annually, disrupting food chains and threatening biodiversity.

Damage to Waterways and Irrigation Systems

Plastic waste often finds its way into rivers, lakes, and irrigation channels, causing significant harm to water systems. It clogs inlets and outlets, obstructing the flow of water necessary for agriculture and human consumption. This not only reduces the efficiency of irrigation but also increases maintenance costs for farmers and municipalities. According to a report by the World Bank, blocked irrigation systems due to plastic waste cost millions annually in lost productivity and repairs. Moreover, plastic contamination affects the quality of water, introducing toxic chemicals that make it unsafe for both agricultural use and drinking.

Impact on Aquatic and Terrestrial Life

The damage extends beyond water systems to the animals that inhabit these ecosystems. Plastic bags, fishing lines, and bottle caps are common culprits that entangle marine and terrestrial animals, leading to suffocation, starvation, or injury. Sea turtles often mistake plastic bags for jellyfish, ingesting them and subsequently suffering fatal blockages in their digestive systems. Birds and mammals become ensnared in discarded fishing nets and ropes, limiting their mobility and causing injuries that can be fatal. The suffocating presence of plastic waste disrupts ecosystems, endangering the biodiversity that sustains life on Earth.

Supermarkets: The Plastic Juggernauts

Plastic-Covered Produce

Supermarkets are among the largest contributors to plastic waste. Their shelves are lined with fruits, vegetables, and salads wrapped in single-use plastics. This practice, often justified as a means to preserve freshness, is a convenience that carries a monumental environmental cost. In countries like here in the UK, supermarkets generate approximately 900,000 tons of plastic packaging waste every year. This plastic not only clogs landfills but also finds its way into waterways and oceans, creating widespread ecological damage. The overuse of plastic in supermarkets is not merely a matter of wastefulness; it is a symptom of a broader cultural dependence on convenience at the expense of sustainability.

Shifting Blame to Consumers

Retailers frequently shift the responsibility of reducing plastic waste onto consumers. Campaigns promoting reusable bags, recycling initiatives, and eco-conscious purchasing habits are well-intentioned but insufficient. These measures often create a false sense of progress while leaving the systemic issues of plastic overproduction unaddressed. Supermarkets have the power to eliminate plastic at the source by adopting alternative packaging solutions or rethinking their display methods. However, without a concerted effort from retailers, the burden of reducing plastic waste continues to fall disproportionately on consumers, many of whom lack the resources or knowledge to make impactful changes.

Short-Term Effects

Plastic pollution has immediate and devastating effects on biodiversity. In marine environments, microplastics are ingested by fish and other aquatic organisms, leading to internal injuries, blockages, and eventual death. This disruption of marine food chains has broader implications, as larger predators depend on these organisms for survival. Terrestrial wildlife is equally affected; animals often mistake plastic debris for food, which can cause choking, starvation, or poisoning. These immediate harms not only diminish wildlife populations but also destabilise ecosystems that are vital for human survival.

Long-Term Effects

The long-term consequences of plastic pollution are even more alarming. As plastics degrade, they release microplastics and toxic chemicals into the soil and water, contaminating the very foundations of life. This contamination disrupts natural processes such as soil fertility and water purification, making it harder for ecosystems to regenerate. Declining biodiversity has cascading effects, reducing the resilience of ecosystems to climate change and other stressors. The World Wildlife Fund warns that the loss of biodiversity jeopardises essential services like pollination, which is critical for food production, and carbon sequestration, which helps mitigate climate change. The long-term impacts of plastic pollution extend beyond environmental degradation, threatening food security, public health, and economic stability.

Biodiversity Under Siege

Plastic pollution has immediate and long-term consequences. Marine animals mistake debris for food and die of starvation or internal injuries. Birds, fish, and mammals become entangled in nets and packaging, unable to escape. Over time, microplastics contaminate the food web, threatening entire ecosystems. Soil fertility, pollination, and carbon cycles — the very foundations of life — are being eroded.
