What Is the Mortality Rate of Animals Due to Plastic Pollution?
05/03/2024
Each year, an immense quantity of plastic infiltrates the global ecosystem due to the staggering levels of plastic production worldwide. A significant portion of this plastic finds its way into water bodies and the world's oceans, leading to profoundly detrimental environmental consequences. A United Nations report forecasts that by 2050, the volume of plastic in the world's oceans will surpass that of fish. Marine life bears a particularly heavy toll from the epidemic of plastic pollution, with many creatures ingesting plastic items, often resulting in fatalities. However, the adverse effects of plastic pollution extend beyond animals.
Plastic Waste Statistics
According to data from Statista, only a mere 15% of the world's plastic waste is actually collected for recycling. The majority ends up in the environment, exerting negative impacts on wildlife. Global plastic production has surged twofold to nearly 400 million metric tons per annum since the turn of the century. Taking recycling rates into account, approximately 340 million tons of plastic waste are projected to accumulate in landfills and similar disposal sites. Plastic Oceans.org reports that a staggering 10 million tons of plastics are dumped into the world's oceans annually, equivalent to a dump truck's load of plastic every minute.
While this may seem like a plausible solution, issues arise when considering the time it takes for plastics to decompose. The average lifespan of plastic products is around ten years, yet certain plastics may take up to 500 years to fully degrade. Even more alarming is the projection that global plastic production will reach 1 billion metric tons by 2060. Although some plastic waste management methods involve incineration, this approach also poses environmental risks due to emissions of pollutants.
Currently, the bulk of plastic waste production is attributed to the UK and US, with China, Indonesia, and Vietnam also significant contributors. While many associate plastic waste with visible items like shopping bags littering shorelines, the issue extends further, with unsuspected products containing microplastics. Face scrubs, soaps, toothpaste, and shower gels have been found to contain microbeads, leading to their prohibition from sale in England and Scotland since 2018. While this marks a positive step, significant efforts are required to address the issue comprehensively.
Impact of Plastic Pollution on Wildlife
Quantifying the precise number of wildlife deaths annually due to plastic pollution is challenging, yet this does not obscure the evident damage inflicted. According to a study by the World Wildlife Fund, approximately 100,000 marine mammals perish each year due to plastics, excluding the countless fish and marine reptiles that ingest plastic debris, making an accurate count elusive. However, numerous marine animals, particularly turtles and fish, are found with plastic debris in their stomachs or entangled in plastic products. This represents only a fraction of the broader problem of ocean pollution affecting marine ecosystems. Seagulls and other wildlife frequently fall victim to plastic pollution, as evidenced by the presence of rubbish and plastics in their digestive systems when washed ashore or tagged by researchers. Moreover, the issue extends beyond the oceans, with many plastic products ending up on shorelines or carried inland, posing hazards to land animals as well.
Ocean Plastic Statistics
According to UNESCO, an estimated 80% of marine pollution results from plastic waste. Trillions of plastic pieces are believed to pollute the world's oceans, with plastic debris discovered even in the most remote oceanic regions, forming islands or "garbage patches" of aggregated plastic waste. With projections indicating that plastic may outweigh fish in the ocean by 2050, the situation appears dire. Marine life ingests these plastics, mistaking them for food, leading to bioaccumulation up the food chain and posing risks to human consumers as well, as contaminated fish stocks become increasingly prevalent.
Microplastics pose a significant threat as they can infiltrate human bodies through various routes, including consumption and inhalation. Even human breast milk has been found to contain microplastics.
Health Risks to Humans
Plastic pollution not only harms the environment and wildlife but also poses health risks to humans. Microplastics can permeate drinking water, food supplies, and even the air we breathe. Remote locations such as Mt Everest now show traces of microplastics, underscoring the global extent of the issue. Commercial tuna cans have been found to contain microplastics, illustrating how deeply embedded plastic pollution has become in the food chain. Additionally, microplastics contain endocrine-disrupting chemicals, which can interfere with human hormones, particularly during critical developmental stages. While the full extent of these chemicals' impact on human health remains unclear, many health experts express concerns. Unfortunately, the complete ramifications of plastic pollution on human health have yet to be fully comprehended, but there are strong indications that increased microplastics and pollution will have detrimental effects.
Plastic Oceans.org estimates that the average person will ingest over 40 pounds of plastic in their lifetime.
Significance of Addressing Plastic Pollution
The repercussions of plastic pollution are extensive, encompassing ecological, economic, and health impacts that may prove catastrophic for future generations unless concerted efforts are made to address the issue. Plastics persist in the environment for extended periods, infiltrating animals and ecosystems, and infiltrating water sources and human food supplies. The carcinogenic properties of microplastics pose long-term health risks, further exacerbating the problem as plastic production escalates. Over the past decade, plastic production has surpassed that of the entire 20th century, underscoring the urgency of action.
What Can Be Done
While many plastic products are unfortunately designed for single-use, making efficient disposal challenging, individuals can take proactive steps to mitigate wildlife impacts by ensuring proper recycling practices. Although seemingly simple, collective participation can yield significant outcomes.
- Recycle plastics responsibly
- Minimize plastic consumption
- Support NGOs working on plastic pollution
- Engage in volunteer opportunities
- Educate oneself on the issue
- Collaborate with groups driving change
While there is no quick fix to plastic pollution, mounting public pressure may compel governments worldwide to enact stronger measures as the problem escalates. In the interim, individual awareness of waste generation and plastic consumption remains crucial in effecting change.
