Trash Pollution: A Deadly Threat To Wildlife

Trash pollution is a significant threat to wildlife, causing harm in several ways. Animals can become entangled in litter, leading to injuries or death, and they may also mistake trash for food, resulting in ingestion of harmful materials. This ingestion can block airways, fill their stomachs, and cause choking or starvation. Additionally, trash can interfere with animals' ability to swim, obtain food, and disrupt their natural behaviours. It can even alter their habitats, behaviour, and reproduction rates. The toxins released from trash can affect both wildlife and plant life, impacting their growth and health. With plastic being a major contributor to littering, the impact on wildlife is severe and far-reaching.

Trash can cause wildlife to suffocate

Trash can also interfere with an animal's ability to move freely. For example, animals can become entangled in plastic debris or abandoned fishing gear, hindering their movement and causing them to drown. This debris can also cut into their skin and cause infections.

Additionally, wildlife often mistakes trash for food. Sea turtles, for instance, may try to eat plastic bags because they resemble jellyfish, one of their natural prey. When they ingest this trash, it can block their airways or fill their stomachs, causing them to choke or starve.

The impact of trash on wildlife depends on various factors, including the size, type, shape, and quantity of the debris, as well as the type of organism exposed and the frequency of exposure. While all types of trash can have harmful effects, plastic waste is of particular concern due to its persistence in the environment and widespread production and disposal.

It can interfere with their ability to move, feed or migrate

Trash pollution can interfere with wildlife's ability to move, feed, or migrate in several ways. One of the most common issues is entanglement, where animals become trapped in plastic waste and other litter. This hinders their movement and can cause severe injuries or even death. For example, birds can become entangled in fishing nets, and marine mammals such as dolphins, seals, and whales often fall victim to entanglement, leading to hundreds of thousands of deaths each year.

Ingesting litter is another significant problem. Animals may mistake trash for food, such as sea turtles eating plastic bags that resemble jellyfish. When ingested, litter can block airways, fill their stomachs, and cause internal organ damage, starvation, or poisoning. It can also decrease their mobility, as seen with white storks in Portugal, who have stopped migrating and now live near landfills, likely consuming plastic particles with every meal.

Litter can also obstruct natural migration routes and disrupt habitats. When litter accumulates and blocks their usual paths, animals' regular migration and habitats are affected, contributing to ecological imbalances. Additionally, animals are drawn to food waste near busy roads, which endangers them due to the risk of collisions with vehicles.

Trash pollution can further impact wildlife by altering their behaviour and reproduction rates. The presence of litter can change an animal's natural behaviour, and artificial light pollution from trash can disrupt their migratory patterns. For example, light from discarded containers or reflective materials can confuse animals that rely on day and night cycles for navigation and feeding.

It can cause internal organ damage and poisoning

Wildlife is often unable to distinguish between food and plastic waste, and in some cases, they are attracted to plastic by its smell. This can lead to internal organ damage and poisoning.

Plastic ingestion can block digestive tracts or pierce internal organs in wildlife. It can also choke and starve animals by making them feel full after eating indigestible plastic. In some cases, plastic consumption can lead to a reduction in stomach storage volume, making it difficult for animals to eat. For example, in 2018, a wild elephant in India died from plastic ingestion, with plastic blocking its intestines and causing internal bleeding and organ failure.

Studies have also confirmed the presence of microplastics in hundreds of species, causing liver and cell damage, as well as disruptions to reproductive systems. For some species, such as oysters, this could mean a reduction in egg production, threatening population growth.

Furthermore, the chemicals released from plastic waste can contaminate the soil and water sources, causing poisoning in animals that ingest or come into contact with these pollutants.

The impact of plastic pollution on internal organ damage and poisoning in wildlife is severe and far-reaching, affecting a wide range of species and threatening their survival.

It can alter habitats, behaviour and reproduction rates

Trash pollution can alter habitats, behaviour, and reproduction rates of wildlife.

Altering habitats

Trash can physically alter the habitats of wildlife. For example, trash that ends up in waterways and bodies of water can block sunlight and deplete oxygen levels, both of which are essential for underwater photosynthesis and the health of aquatic plants and animals. It can also ignite fires, which can be challenging to control and pose a significant risk to wildlife and their habitats.

Behaviour

Trash pollution can also impact the behaviour of wildlife. Animals may mistake trash for food, leading to ingestion of harmful materials and internal organ damage. For example, sea turtles may mistake plastic bags for jellyfish, their natural prey. Birds can be particularly susceptible to bright-coloured pieces of trash, such as balloons, which they cannot digest and which can lead to starvation. Trash can also confuse animals that rely on day and night cycles, as artificial light pollution can disrupt their natural behaviours and migratory patterns.

Reproduction rates

Trash pollution can impact reproduction rates by affecting the health of animals. For example, the ingestion of litter can decrease an animal's mobility, poison them, and even lead to death. Additionally, the accumulation of trash in certain areas can obstruct natural migration routes and disrupt habitats, further impacting reproduction rates.

It can increase body temperatures to harmful levels

Trash pollution is a significant threat to wildlife, and one of the ways it can harm them is by increasing their body temperatures to harmful levels. This is especially true for marine wildlife, which is already adapted to living in a certain temperature range. When trash, such as plastic bags, is introduced into the water, it can interfere with the animal's ability to regulate its body temperature. This is because trash can act as an insulator, trapping heat and preventing it from escaping. This can lead to a rise in the animal's body temperature, which can be harmful or even fatal.

For example, sea turtles are particularly vulnerable to the effects of trash pollution. As they swim through polluted waters, plastic bags can get tangled around their shells or flippers, hindering their movement and making it difficult for them to escape to cooler waters. Additionally, when sea turtles ingest plastic, it can block their digestive system, leading to a build-up of heat-generating bacteria in their gut. This can further contribute to an increase in body temperature.

Trash pollution can also affect the thermoregulation of birds and other wildlife. As debris accumulates in their nests or habitats, it can trap heat, raising the overall temperature of their living environment. This can be detrimental to the health and development of young animals, as well as interfere with breeding cycles.

Furthermore, the colour of the trash can also impact wildlife body temperatures. Darker-coloured trash, such as black plastic fragments, can absorb more heat from the sun. This not only raises the temperature of the surrounding water or air but also of any animal that ingests it. As the plastic breaks down into microplastics, these tiny particles can be consumed by smaller creatures, such as fish or crustaceans, leading to a build-up of harmful toxins and heat in their bodies.

The impact of trash pollution on wildlife body temperatures is a serious concern, and it underscores the importance of proper waste management and disposal. By reducing the amount of trash that ends up in natural habitats, we can help mitigate the harmful effects it has on wildlife, including the risk of increased body temperatures.
