Plastic waste can cause intestinal blockages and damage, leading to death
Plastic waste is a significant threat to wildlife, with over 800 species affected by plastic marine debris worldwide. Animals can easily mistake plastic for food, leading to ingestion, which can cause intestinal blockages and damage, and even death.
Ingesting plastic can lead to intestinal blockages, preventing the animal from digesting food properly and causing malnutrition and starvation. Plastic waste can also damage the intestinal walls, leading to internal bleeding and infection. This was seen in a wild elephant in Periyar, India, which died from ingesting plastic waste discarded by pilgrims. The plastic blocked the elephant's intestines, causing internal damage and eventually leading to its death.
Young animals are particularly vulnerable to ingesting plastic as they are less selective about what they eat and tend to drift with ocean currents, where plastic debris often accumulates. A study found that sea turtles that ingest just 14 pieces of plastic have an increased risk of death. Similarly, scientists predict that 60% of all seabird species have eaten plastic, and this number is expected to rise to 99% by 2050 if plastic pollution continues unchecked.
Plastic waste in oceans and landfills can break down into microplastics, which are then ingested by smaller creatures, such as mites, larvae, and other soil fauna. This leads to a decrease in these species, resulting in less fertile soil and land. Microplastics can also contaminate groundwater, further impacting wildlife and humans.
Additionally, plastic waste can become entangled around animals, causing deep cuts and wounds that increase the risk of deadly infections. Marine mammals, such as humpback dolphins, have been observed with plastic debris tightly wrapped around their bodies. Abandoned fishing gear, such as nets and lines, is a significant contributor to entanglement, affecting 81 out of 123 marine mammal species.

Plastic waste can be mistaken for food, increasing the risk of ingestion
Plastic waste is a pressing issue that affects all wildlife, including those in the ocean and on land. It is estimated that 13 million metric tons of plastic end up in the ocean each year, with plastic debris affecting at least 800 species worldwide. The ingestion of plastic waste is a significant concern, as animals can mistake it for food, leading to increased ingestion and severe health risks.
Marine animals, such as sea turtles, are particularly vulnerable to ingesting plastic waste. A recent study found that sea turtles that ingest just 14 pieces of plastic have an increased risk of death. Young turtles are especially at risk due to their less selective feeding habits and tendency to drift with ocean currents, similar to floating plastic debris. Sea turtles can mistake floating plastic bags for their natural prey, such as jellyfish, leading to fatal blockages in their digestive systems.
Seabirds are another group that is highly susceptible to ingesting plastic waste. Plastic debris can fill their stomachs, leading to starvation and death. Scientists estimate that 60% of all seabird species have ingested plastic, and this number is predicted to rise to 99% by 2050. Seabird chicks, like the albatross chick found dead on Midway Atoll with plastic debris in its stomach, are particularly vulnerable to mistaking plastic for food.
Terrestrial animals are also affected by plastic waste ingestion. In a tragic example, a 20-year-old wild elephant in Periyar, India, died from ingesting plastic waste discarded by pilgrims. Elephants, along with other land-based mammals such as hyenas, zebras, and camels, accidentally consume plastic waste, leading to unnecessary deaths and highlighting the far-reaching consequences of plastic pollution.
Additionally, microplastics, tiny particles resulting from the breakdown of larger plastics, contaminate soil and water sources. A 2020 study revealed that terrestrial microplastic pollution has led to a decline in species that live below the surface, such as mites and larvae, reducing soil fertility. The presence of microplastics in the environment means that the food we grow and wildlife consumes is likely to be contaminated, impacting both animals and humans alike.

Plastic waste can encourage the growth of pathogens in the ocean, increasing the likelihood of disease
Plastic waste is detrimental to wildlife, including those in the ocean and on land. It can take hundreds of years for plastic to fully decompose, but some break down into microplastics much faster. These microplastics can be ingested by marine animals and end up in the seafood that humans consume.
Plastic waste in the ocean can encourage the growth of pathogens, increasing the likelihood of diseases in animals. Corals that come into contact with plastic have an 89% chance of contracting diseases, compared to a 4% likelihood for corals that do not. Marine mammals, such as humpback dolphins, have been observed with plastic debris wrapped tightly around their bodies, leaving them vulnerable to deadly infections.
In addition to entanglement, ingestion of plastic waste is a significant issue for marine animals. Sea turtles, for example, face an increased risk of death when they ingest plastic, as it takes up room in their stomachs and can cause intestinal injuries, sometimes leading to starvation. Similarly, plastic debris in the stomachs of seabirds has been linked to starvation and death, with an estimated 60% of all seabird species having eaten plastic.
The impact of plastic waste on wildlife is not limited to the ocean. Land-based mammals, including elephants, hyenas, zebras, and camels, have accidentally consumed plastic waste, resulting in intestinal blockages and fatalities. Microplastics from landfills and other environments can contaminate soil and water sources, leading to a decline in species that live below the surface and negatively impacting the fertility of the soil.
The presence of plastic waste in the environment poses a threat to various animal species, both in the ocean and on land. It increases the likelihood of disease transmission and contributes to the decline in animal populations. Addressing this issue requires collective efforts to reduce, recycle, and properly dispose of plastic waste.

Plastic waste can cause entanglement, restricting movement and leading to drowning
Plastic waste is detrimental to wildlife, both in the ocean and on land. It can take hundreds of years to break down, persisting in the environment and causing harm to countless animals. One of the primary ways plastic harms animals is through entanglement, which can restrict movement and lead to drowning.
Entanglement in plastic waste can have devastating consequences for animals, hindering their ability to move freely and perform essential tasks such as hunting or migrating. Marine mammals, in particular, are at risk of becoming entangled in plastic debris, including abandoned fishing gear and nets. This entanglement can be life-threatening, as it may restrict their movement, making it difficult for them to swim, escape predators, or reach the surface to breathe.
Young sea turtles are especially vulnerable to entanglement, as they tend to drift with ocean currents, similar to floating plastic debris. When entangled, they may be unable to reach the surface to breathe, leading to drowning. Additionally, plastic waste can entangle and restrict the growth of fish, such as the blue-striped grunt fish in the Caribbean Sea.
Entanglement in plastic waste can also cause deep wounds and lacerations, leaving animals susceptible to deadly infections. For example, humpback dolphins, a rare species found only in the waters around Australia and New Guinea, have been observed with marine debris tightly wrapped around their bodies. If not dislodged, this plastic waste can cut into their skin, causing severe injuries and increasing the risk of infection.
Plastic entanglement is a significant issue for birds as well. They can become entangled in plastic debris, leading to restricted movement and, in some cases, drowning. Furthermore, plastic waste can ensnare and harm land-based mammals, such as elephants, hyenas, zebras, and camels, causing unnecessary suffering and death.

Plastic waste can contaminate soil and water sources, impacting terrestrial animals
Plastic waste is detrimental to wildlife, including those in the ocean and on land. It can take hundreds of years to break down into smaller pieces, which can be easily ingested by animals. Plastic waste can contaminate soil and water sources, impacting terrestrial animals.
A 2020 study found that microplastics in soil led to a decrease in species living below the surface, such as mites, larvae, and other tiny creatures. These species are essential for soil fertility and health. Chlorinated plastic, such as food packaging and medical devices, can release harmful chemicals into the surrounding soil and groundwater, which many species rely on for survival. The food we grow and wildlife consume is likely to be contaminated with microplastics. For example, fruits like apples and pears have been found to contain a high number of microplastic particles.
Plastic waste in the ocean is also a significant concern for marine life. It can take the form of floating debris or break down into microplastics, which are easily ingested by marine animals. Sea turtles, for instance, have an increased risk of death when they ingest as few as 14 pieces of plastic. Seabirds are also affected, with plastic waste taking up room in their stomachs and causing starvation.
The impact of plastic waste on terrestrial and marine animals highlights the urgent need to address plastic pollution. Reducing plastic waste, improving recycling rates, and finding alternatives to harmful chlorinated plastics are essential steps towards mitigating the negative impacts of plastic on the environment and wildlife.
