Plastic pollution is a pressing environmental issue, with global plastic pollution jumping from two million tonnes in 1950 to 348 million tonnes in 2017. It is projected to double by 2040. Plastic waste is harmful to wildlife and humans, with plastic pollution causing the deaths of over 100 million marine animals every year. Marine animals are affected by plastic pollution through entanglement, ingestion, and toxic contamination. Similarly, plastic pollution affects animals on land. Animals on land are at risk of being trapped in plastic waste, and they can also accidentally consume plastic, which can cause intestinal blockages and damage and even lead to death. Microplastics, which are small plastic particles, can also contaminate the soil and water sources that land animals rely on.

Plastic ingestion causes intestinal blockages and damage, leading to animal deaths
Plastic pollution is a pressing issue that affects all wildlife, including animals on land. One of the most detrimental impacts of plastic pollution on land animals is intestinal blockage and damage caused by plastic ingestion, which often leads to death.
Land animals, just like their marine counterparts, are susceptible to ingesting plastic waste that has been discarded in their habitats. This ingestion of plastic can result in intestinal blockages, causing severe internal damage and even death. In January 2018, a wild elephant in Periyar, India, died due to plastic ingestion. An autopsy revealed that plastic waste had blocked the elephant's intestines, leading to internal bleeding and organ failure. This is not an isolated incident, and several land-based mammals, including hyenas, zebras, tigers, camels, and cattle, have suffered similar fates.
The presence of plastic in the intestines can prevent food from passing through the digestive system, leading to malnutrition and starvation. Additionally, sharp edges on plastic debris can cause lacerations and internal injuries. Furthermore, plastics often contain toxic chemicals, such as BPA and phthalates, which can leach into the animal's body, causing poisoning and weakening their immune systems. These chemicals are known endocrine disruptors, interfering with hormone functioning and leading to reproductive issues and developmental abnormalities.
The impact of plastic ingestion on land animals can also have sub-lethal consequences, such as reduced body condition, physiological changes, and increased chemical burden. These effects may not directly cause mortality but can decrease an animal's chances of survival and reproduction. For example, research has shown that earthworms exhibit reduced fitness when microplastics are present in the soil, and their burrowing behaviour is altered, further damaging the forest ecosystem.
Microplastics, small plastic particles less than 5mm in size, are of particular concern. They can easily be ingested by land animals and accumulate in their bodies. Microplastics can release additives and chemicals, causing harm to the hormone systems of vertebrates and invertebrates. As plastics break down into smaller pieces, they become more accessible to land animals, and their toxic effects can have widespread consequences on terrestrial ecosystems.

Animals get trapped and entangled in plastic waste, affecting their mobility
Animals on land are greatly affected by plastic waste. They often get trapped and entangled in plastic, which affects their mobility and can lead to reduced mobility, starvation, or suffocation. It can also cause infections, growths, or amputation of limbs. Land-based mammals, including elephants, hyenas, zebras, tigers, camels, and cattle, have accidentally consumed plastic waste, resulting in unnecessary deaths. For example, in 2018, a wild elephant in India died from ingesting plastic discarded by pilgrims. The plastic blocked the elephant's intestines, causing internal bleeding and organ failure.
Plastic pollution is a significant issue, with global plastic pollution jumping from two million tonnes in 1950 to 348 million tonnes in 2017 and is projected to double by 2040. This has led to an increase in plastic waste in unprotected wild lands and forests, endangering the animals that live there. Animals can get entangled in plastic, such as packing bands, plastic bags, and six-pack rings, which can restrict their movement and make them more vulnerable to predators.
The impact of plastic pollution on wildlife is devastating, and it is essential to address this issue to protect animals on land and in water. Plastic waste can entangle and trap animals, affecting their mobility and ability to survive. It is crucial to reduce plastic consumption, increase recycling efforts, and properly dispose of plastic waste to mitigate the impact on wildlife.
Furthermore, plastic waste can entangle animals, making them more vulnerable to predators. For example, a trapped animal may not be able to run away from a predator or hide effectively due to the plastic restricting its movement. This increases the likelihood of the animal becoming a victim of predation, further endangering their survival.
The effects of plastic entanglement on animals' mobility can be immediate and long-term. In the short term, animals may struggle to move freely and escape danger, or access necessary resources like food and water. This can lead to starvation and dehydration, and increased vulnerability to predators. Over time, entanglement can cause injuries, infections, and growths, and permanent disabilities, further reducing their ability to survive in the wild.

Microplastics in soil affect the fitness of earthworms and the soil condition
Plastic pollution is a pressing issue that affects all wildlife, including land animals. Microplastics, in particular, have been detected in soil and freshwater, with terrestrial microplastic pollution estimated to be four to 23 times higher than marine microplastic pollution.
Earthworms, for example, are known to ingest microplastics in the soil, leading to weight loss and potentially impairing their ability to contribute to soil health. Earthworms play a crucial role in creating healthy soil by burrowing and consuming organic matter, and their excrement, or castings, contain essential nutrients like nitrogen and phosphorus that promote plant growth. However, the presence of microplastics in the soil affects earthworm behaviour, causing them to construct their burrows differently. This alteration in behaviour may have a detrimental impact on both the fitness of the earthworms and the overall soil condition.
Studies have found that microplastics in soil can stunt the growth of earthworms. For instance, a 21-day experiment examined the impact of different sizes of polyethylene microbeads on earthworms. The results indicated that smaller microbeads were transported to greater depths in the soil by the earthworms, demonstrating their ability to act as transport agents for microplastics. Furthermore, the presence of microplastics in the soil can lead to a decline in other soil fauna, such as mites and larvae, which are crucial for maintaining soil fertility.
The accumulation of microplastics in soil is a growing concern, and further research is needed to fully understand its impact on land ecosystems and the animals that inhabit them.

Microplastics in food chains release additives that disrupt the hormone systems of vertebrates and invertebrates
Microplastics, defined as plastic particles smaller than 5mm, are a major concern for animals on land. They are present in every corner of the environment, from the soil to the air, and can easily enter the human food chain through ingestion, inhalation, and skin contact.
Microplastics in food chains can release additives such as phthalates and Bisphenol A (BPA), which can disrupt the hormone systems of both vertebrates and invertebrates. These hormonal disruptions can lead to adverse effects on reproduction and development, impacting the survival of various species.
In a 2020 study, it was found that terrestrial microplastic pollution decreased the population of mites, larvae, and other small creatures living below the surface. This decline in soil fauna leads to reduced soil fertility and ecosystem health. Chlorinated plastics, such as food packaging and medical devices, can also release harmful chemicals into the soil and groundwater, further contaminating the food sources of wildlife and humans alike.
The impact of microplastics on wildlife and humans has raised global concerns. Plastic pollution has led to the deaths of millions of marine animals and is equally harmful on land. Animals can suffer intestinal blockages and damage from ingesting plastic, leading to unnecessary deaths. For example, a wild elephant in India died from internal bleeding and organ failure caused by plastic ingestion.
The widespread presence of microplastics in the environment and food chains highlights the urgent need for strict regulations and proper waste management to mitigate their harmful effects on both animal and human health.

Plastic waste dumped in unprotected wild land puts wild animals in danger
The dumping of plastic waste in unprotected wild land also affects the soil and the species that reside within it. Microplastics, originating from plastic waste in landfills and other environments, contaminate the soil and seep into groundwater, leading to a decline in species that live below the surface, such as mites, larvae, and other tiny creatures. Chlorinated plastic, commonly found in food packaging and medical devices, further exacerbates this issue by releasing harmful chemicals into the surrounding soil and water sources.
In addition to the direct impact on animals, plastic waste in unprotected wild land also has indirect effects on wildlife. The reduction in soil-dwelling species due to microplastic pollution results in less fertile soil, negatively impacting the flora and fauna that depend on healthy soil ecosystems. Earthworms, for example, exhibit altered burrow-building behaviour in the presence of microplastics, which, in turn, affects soil conditions and the dependent forest flora.
The accumulation of plastic waste in unprotected wild land also poses entanglement risks for wild animals, hindering their mobility and increasing their vulnerability to predators. This danger is not limited to land animals, as plastic waste can be transported by rivers and other water sources, ultimately reaching oceans and affecting marine life. The impact of plastic pollution is widespread, with nearly 2,100 species, including endangered ones, known to be affected.
To address the dangers posed by plastic waste dumping in unprotected wild land, it is crucial to reduce plastic consumption and promote plastic reuse. These actions will help decrease the amount of plastic circulating through trash piles that can reach soil and forest ecosystems, thereby mitigating the risks to wild animals and preserving the delicate balance of nature.
