What You'll Learn
Plastic ingestion
Seabirds are particularly vulnerable to plastic ingestion, with an estimated 32% to 60% of all seabird species having eaten plastic. This number is predicted to increase to 99% by 2050. Dead seabirds are often found with stomachs full of plastic, indicating the severity of the issue. Plastic debris blocks their intestinal tracts, leading to starvation and death. The problem is not limited to seabirds; thousands of sea turtles, seals, whales, dolphins, and other marine mammals are also affected by plastic ingestion. Research indicates that half of the sea turtles worldwide have ingested plastic, mistaking it for food.
Terrestrial animals are not immune to the dangers of plastic ingestion. Deer in Japan and the UK have been found dead with significant amounts of plastic in their stomachs. Arabian camels also face a similar fate, with half of the population dying each year from ingesting plastic bags. Elephants in India and Africa have also succumbed to plastic ingestion, highlighting the global reach of this issue.
The effects of plastic ingestion extend beyond the individual animal. When plastic-filled animals decompose, the plastic is released back into the environment, where it can be ingested by other organisms. This creates a cycle of pollution and harm, disrupting ecosystems and reducing biodiversity. Additionally, the decline in marine animal populations due to plastic ingestion can alter food web dynamics and impair essential ecosystem services like carbon sequestration and nutrient cycling.
Addressing plastic ingestion in animals requires a multi-pronged approach. Reducing plastic production and consumption, improving waste management, and increasing recycling efforts are crucial steps in mitigating this global crisis. Individual actions, such as eliminating single-use plastics and volunteering for cleanup efforts, can also make a significant difference in protecting wildlife and aquatic habitats.

Entanglement in plastic debris
Plastic pollution has been a problem for almost as long as plastic has existed. It affects the environment and all the organisms that live in it, entangling, choking, strangling, and starving animals, from the largest mammals to the smallest crustaceans.
The Impact of Entanglement in Plastic Debris
Examples of Entanglement in Plastic Debris
- Endangered wildlife like Hawaiian monk seals and Pacific loggerhead sea turtles are among the nearly 700 species that eat and get caught in plastic litter.
- Packing bands, the most common entangling material, have led to injury and mortality in the endangered Steller sea lion.
- Discarded fishing gear has entangled and killed 300,000 cetaceans.
- A Japanese Nara Park deer was discovered dead with 4.3 kilograms of plastic in its stomach, and deer in the UK face a similar problem.
- Half of Arabian camels die each year from ingesting plastic bags.
- An Indian elephant died in 2018 from eating plastic shopping bags, and eight African elephants died in 2016 after eating plastic bread bags.

Chemical contamination
Plastic pollution is a critical environmental issue that poses a significant threat to both marine and terrestrial animals. While it is challenging to estimate the exact number of animal deaths caused by chemical contamination from plastic pollution, the impact is undoubtedly severe and far-reaching.
Marine animals, including fish, sea turtles, whales, dolphins, and coral reefs, are particularly vulnerable to chemical contamination from plastic pollution. For example, over half of fish stocks had ingested plastic as of 2018, introducing toxic substances into their bodies and impairing their ability to obtain adequate nutrition. This not only poses a threat to their health and survival but also has broader ecological implications, as these marine creatures are vital for both the oceanic ecosystem and human consumption.
Terrestrial animals are also affected by chemical contamination from plastic ingestion. Grazing animals, such as deer and camels, are known to consume plastic debris, especially when coated with food waste. This ingestion can lead to internal deterioration and poisoning, causing significant harm to their health and survival.
The impact of chemical contamination from plastic pollution extends beyond individual animals, threatening entire ecosystems. For instance, plastic pollution damages coral reefs, leading to disease and bleaching. This, in turn, affects the fish and other marine life that depend on the coral reef as their habitat. As a result, the entire ecosystem becomes vulnerable to disruption and potential collapse.
While the full magnitude of the problem remains unclear, it is evident that plastic pollution, including chemical contamination, plays a significant role in the ongoing environmental and animal crisis. To protect our planet's biodiversity and ensure the survival of various species, it is imperative to address plastic pollution through individual actions, global efforts, and policy changes.

Plastic pollution in land animals
Plastic pollution is a significant issue for land animals, causing intestinal blockages and damage when ingested. This has resulted in the deaths of various land-based mammals, including elephants, hyenas, zebras, tigers, camels, and cattle. For instance, a wild elephant in Periyar, India, died in January 2018 from ingesting plastic waste, which blocked its intestines and caused internal bleeding and organ failure.
The impact of plastic pollution on land animals is comparable to that on marine animals. Land animals can become entangled in plastic waste, restricting their mobility and making them vulnerable to predators. They may also mistake plastic for food, leading to choking and poisoning. This issue is not limited to wild animals, as domestic animals like dogs and cows are also affected by ingesting plastic or having their heads trapped in plastic containers, leading to suffocation, dehydration, and starvation.
Microplastics, which come from the breakdown of larger plastics, are another concern for land animals. They can leech into the soil and water sources from landfills and other environments, contaminating the food we grow and impacting the wildlife that consumes it. A 2020 study found that terrestrial microplastic pollution has led to a decline in species that live below the surface, such as mites, larvae, and other tiny creatures, reducing soil fertility.
Additionally, chlorinated plastic, such as food packaging and medical devices, can release harmful chemicals into the surrounding soil and groundwater, further endangering the health of land animals and humans alike. The best way to combat this issue is to reduce plastic consumption and properly dispose of and recycle plastics to prevent them from ending up in landfills and the environment.
The fashion industry also plays a role in plastic pollution, with microplastics from synthetic clothing fibers being discharged into the environment during washes. Supporting sustainable and circular fashion brands that use recycled materials and designing clothing for durability and reuse can help mitigate the impact on land animals.

Human negligence
Plastic pollution is a critical environmental issue that has far-reaching impacts on marine animals, and it is a direct result of human negligence. The amount of plastic waste in the ocean is growing rapidly, and it is wreaking havoc underwater, killing or crippling marine animals. While it is challenging to estimate the exact number of animals that die from plastic pollution, the impact is significant, and the numbers are still rising.
Ingestion of plastic is a significant issue for marine animals, as it can block their digestive systems and lead to starvation. Sea turtles, for example, often mistake plastic bags for jellyfish and eat them. This mistake is not limited to sea turtles, as other marine animals, such as whales, dolphins, seals, and sea birds, also ingest plastic. A study found that 32% of seabirds have ingested plastic debris, and hard plastics like microplastics and pellets are the biggest culprits. Even land animals like deer and camels are affected, with reports of their deaths caused by ingesting plastic.
Entanglement in plastic is another consequence of human negligence that harms marine animals. Abandoned fishing gear, such as nets and lines, can entangle and choke ocean animals, leading to injuries, suffocation, or drowning. It is estimated that discarded fishing gear has entangled and killed 300,000 cetaceans. Even if the entangled animal is freed, the deep cuts made by the plastic can become infected or attract predators.
Chemical contamination from plastic pollution also poses a significant threat to marine animals. Plastic can contain toxic additives that are released into the water and enter the food chain. These toxins can cause inflammation and other health issues in animals that ingest them, and they can also harm the reproductive systems of marine animals.
While the specific number of animal deaths caused by plastic pollution is challenging to determine, it is evident that human negligence in the form of plastic pollution has devastating consequences for marine life. The impact of plastic on marine ecosystems is severe and widespread, affecting over 690 marine species. To address this issue, individuals and organizations must work together to reduce plastic pollution and protect marine life.
