Plastic ingestion
Plastic pollution is a global crisis, with billions of pounds of plastic in the oceans. Marine species are particularly vulnerable to ingesting plastic. Sea turtles, for example, can mistake floating plastic garbage for food, choking and sustaining internal injuries, or starving as their stomachs fill with plastic. Research indicates that half of sea turtles worldwide have ingested plastic, with plastic found in 86% of all sea turtle species. Similarly, plastic ingestion has been observed in hundreds of thousands of seabirds, reducing the storage volume of their stomachs and causing starvation. It is estimated that plastic has been ingested by 60% of all seabird species, with predictions that this will increase to 99% by 2050. Marine mammals are also at risk of ingesting plastic, with plastic found in 43% of all marine mammal species. Overall, plastic is estimated to contribute to the deaths of more than 100,000 marine mammals annually, including endangered species such as Hawaiian monk seals and Pacific loggerhead sea turtles.
Terrestrial animals are also affected by plastic ingestion. Microplastics, tiny plastic particles less than 5mm long, can leech into the soil and water sources from landfills and other environments. A 2020 study found that terrestrial microplastic pollution decreased populations of mites, larvae, and other small creatures, leading to reduced soil fertility. Chlorinated plastic can also release harmful chemicals into the soil and groundwater, contaminating food sources and impacting wildlife health.
The impact of plastic ingestion on wildlife is severe and widespread, affecting ecosystems and species ranging from microscopic animals to large marine mammals. With plastic pollution expected to increase in the coming years, the threat of plastic ingestion to wildlife is a pressing global issue that requires urgent attention and action.

Entanglement and entrapment
Plastic pollution is a pressing issue that affects all land, freshwater, and marine ecosystems. It poses a serious threat to wildlife, causing entanglement and entrapment, ingestion, and internal injuries. The impact of plastic pollution is widespread, with an estimated 20 million metric tons of plastic polluting the environment annually. This crisis demands urgent attention and action to safeguard our planet's biodiversity.
The presence of plastic in natural habitats poses a significant risk of entanglement and entrapment for wildlife. Large plastic items, such as discarded fishing nets, ropes, and nets, can ensnare marine mammals, fish, and other creatures, impeding their movement and ability to escape. This often leads to starvation, injury, and increased vulnerability to predators. For example, turtles, seals, and other marine mammals frequently become entangled in plastic debris, causing them to drown.
Endangered species are particularly vulnerable to the dangers of plastic pollution. The Hawaiian monk seal, an endangered species, is one of the many victims of plastic entanglement. Nearly 700 species, including endangered wildlife, suffer from the impacts of plastic litter, highlighting the urgent need for conservation efforts.
In addition to marine life, birds are also susceptible to entanglement in plastic. Birds may become trapped in plastic six-pack rings or entangled in other plastic debris, hindering their flight and survival. This issue extends to birds of all sizes, from small songbirds to large birds of prey.
The entanglement and entrapment caused by plastic pollution not only harm individual animals but also disrupt entire ecosystems. For instance, discarded fishing nets can smother and damage coral reefs, hindering their healthy growth. This, in turn, affects the marine life that depends on these ecosystems for food, shelter, and reproduction.
As plastic pollution continues to increase, the risks of entanglement and entrapment for wildlife grow more acute. It is essential to address this issue through responsible waste management, reduced plastic consumption, and global collaborative efforts to protect our planet's biodiversity and ensure the well-being of all species affected by this crisis.

Habitat disruption
Plastic pollution is a pressing issue that affects all land, freshwater, and marine ecosystems. It poses a significant threat to wildlife by disrupting their natural habitats and making it difficult for them to survive and reproduce.
One of the primary ways plastic disrupts habitats is by polluting the soil and water sources. Microplastics from plastic waste in landfills and other environments can leech into the soil and nearby water bodies. This pollution has been found to decrease the populations of mites, larvae, and other small creatures that live below the surface. The decline in these species negatively impacts soil fertility and the health of the ecosystem. Chlorinated plastic, such as plastic food packaging and medical products, can also release harmful chemicals into the soil and groundwater, further contaminating the environment and threatening the survival of species that depend on these resources.
Plastic pollution in oceans and other water bodies has a devastating impact on marine life. Large pieces of plastic can entangle marine animals, restricting their movement, causing injury, and making them more vulnerable to predators. Discarded fishing nets and ropes can smother and damage coral reefs, disrupting the habitat of numerous marine species. Additionally, marine animals often mistake floating plastic debris for food, leading to choking, internal injuries, and starvation. Sea turtles, for example, are particularly affected, with research indicating that half of sea turtles worldwide have ingested plastic.
The accumulation of plastic waste in natural habitats also affects the reproductive success of some species. Studies have shown that plastic pollution on beaches has impacted the reproduction of sea turtles. Oysters are another example, as they may produce fewer eggs when exposed to plastic pollution, threatening their population growth.
Furthermore, plastic pollution can facilitate the spread of invasive alien species, which are a leading cause of biodiversity loss and species extinction. Floating plastics can transport these invasive species to new ecosystems, further disrupting the natural balance and habitat of native species.
Overall, plastic pollution poses a significant threat to wildlife habitats, impacting the survival, reproduction, and overall health of various species across different ecosystems.

In addition to physical injuries, plastic pollution can also cause chemical poisoning in wildlife. Chlorinated plastic can release harmful chemicals into the soil and groundwater, which can then be ingested by animals, causing internal damage. Microplastics are a particular concern, as they can be ingested by terrestrial animals and accumulate in their bodies, leading to potential long-term health effects that are not yet fully understood.
The impact of plastic pollution on internal injuries in wildlife is widespread and devastating. It affects a wide range of species, from large mammals like elephants to smaller creatures like mites and larvae. The ingestion of plastic can lead to intestinal blockages, organ damage, and internal bleeding, causing suffering and death among affected animals.
To protect wildlife from internal injuries caused by plastic pollution, it is essential to reduce plastic consumption and dispose of plastic waste safely. By minimizing the amount of plastic that enters the environment, we can help reduce the suffering and death of countless animals affected by this global issue.

Climate change contribution
Plastic pollution is a pressing issue that affects all land, freshwater, and marine ecosystems. It is a significant contributor to climate change, driving biodiversity loss and ecosystem degradation. Here are some ways plastic pollution contributes to climate change:
Pollution of Ecosystems
Plastic pollution has infiltrated all ecosystems, including land, freshwater, and marine environments. This pollution comes from a variety of sources, such as urban and stormwater runoff, littering, industrial activities, tyre abrasion, construction, and agriculture. In the oceans, plastic pollution originates primarily from land runoff and includes paint shed from shipping and discarded fishing gear. This widespread pollution has a direct and deadly impact on wildlife, affecting their health and survival.
Biodiversity Loss
Plastic pollution is a major driver of biodiversity loss. It harms various species, from microscopic animals to large predators. In the oceans, it is estimated that plastic kills 1 million seabirds and 100,000 marine mammals, turtles, and fish annually. Sea turtles, for example, can choke on plastic or suffer internal injuries, leading to death or starvation as they feel full from ingesting plastic. Research indicates that half of the sea turtles worldwide have ingested plastic, and similar issues are seen in other marine species.
Ecosystem Degradation
The degradation of ecosystems due to plastic pollution further contributes to climate change. In marine environments, plastic pollution smothers and breaks coral reefs, hindering their healthy growth. On land, plastic waste leeches into the soil, reducing its fertility and harming the species that live within it. This degradation of natural ecosystems not only affects conservation efforts but also impacts economies and human well-being. For instance, healthy mangroves provide coastal protection, while wetlands are essential for freshwater provision.
Release of Harmful Chemicals
Chlorinated plastic, such as plastic food packaging and medical devices, can release harmful chemicals into the surrounding soil and groundwater. This contamination affects both wildlife and humans, as the food we grow and consume is likely to be contaminated with microplastics. These microplastics have been found to cause liver and cell damage and disrupt reproductive systems in wildlife.
Transboundary Issue
Plastic pollution is a global issue that transcends borders. It affects unprotected wild land and vulnerable species within them. Without intervention, the amount of plastic pollution is expected to increase significantly by 2040, exacerbating its contribution to climate change. A global plastics treaty is necessary to reduce plastic production, phase out harmful products, and implement strong national plans and rigorous reporting mechanisms.
