Plastic's Deadly Impact On Marine Life

how much marine life is killed by plastic

Marine life is suffering irreparable damage from the chemical pollution of the waters and the millions of tons of plastic waste dumped in the oceans each year. It is difficult to know the exact number of marine animals that die from plastic pollution, but the impact is significant. It is estimated that at least 100,000 marine animals die from plastic pollution each year, with over 100 million marine animals lost every year. This number is likely an underestimate, as it is challenging to determine the cause of death of marine animals, and the majority of deaths go unobserved. Plastic pollution affects marine animals in two main ways: ingestion or entanglement in plastic-based fishing gear. Sea turtles, for example, often mistake plastic bags for jellyfish and eat them, blocking their digestive systems and leading to starvation. Marine mammals, such as whales and dolphins, can also drown when entangled in plastic debris.

Plastic ingestion blocks digestive systems, causing starvation

Marine life is suffering irreparable damage from the chemical pollution of the oceans and the millions of tons of mismanaged plastic waste dumped annually. It is difficult to know the exact number of marine animals that die from ingesting plastic, but the impact is significant. It is estimated that plastic pollution kills 100,000 marine mammals yearly, with 81 out of 123 marine mammal species known to have ingested plastic.

Sea turtles, for example, often mistake plastic bags for jellyfish and eat them. Once ingested, plastic can block their digestive systems, giving them a false sense of fullness and leading to starvation. A review by Kühn and van Franeker estimated that 32% of turtles have plastic marine debris in their stomachs. This plastic debris can also pass entirely through the digestive system, causing internal injuries and intestinal blockage. Sharp or rough plastic can create cuts in the digestive system, leading to infection and internal bleeding.

Additionally, plastic can carry harmful pollutants. They may absorb pollutants from the water or release chemicals added during production. These chemicals may enter an animal's body if ingested, leading to health issues. Research has shown that chemicals added during plastic production can disrupt the endocrine system and hormones regulating growth and development.

The impact of plastic ingestion on human health is also a growing concern. Studies indicate that humans may be consuming tiny fragments of plastic with almost every bite of food. Research suggests that chemicals from microplastics can cross the barriers of cells and cause oxidative stress, initiating tissue damage.

Entanglement in plastic leads to suffocation, drowning, or severe infection

Marine life is suffering irreparable damage from the millions of tons of plastic waste dumped in the oceans each year. Almost 1,000 species of marine animals are impacted by ocean pollution, and over 100 million marine animals die every year. While it is challenging to estimate the exact number of deaths caused by plastic pollution, the impact is significant, and plastic pollution is a leading cause of marine deaths.

Entanglement in plastic is one of the primary causes of death by plastic pollution. Marine animals, such as whales, dolphins, seals, sea lions, and sea turtles, often become entangled in plastic fishing gear and other debris as they swim or while on the beach. Many animals find it difficult to escape entanglement, leading to drowning or death from injury and starvation. Smaller marine animals, like sea turtles, seals, and dolphins, may drown immediately if the plastic gear is large or heavy. Large whales, on the other hand, can usually pull the gear off the ocean floor and are not typically at immediate risk of drowning. However, they may still face exhaustion and infection.

Entanglement can cause severe wounds and infections as the plastic cuts deep into the animal's skin. It can also lead to malnutrition when it prevents the animal from feeding properly. In some cases, entanglement may result in suffocation, as seen in a case where a Kemp's ridley sea turtle in Florida was found entangled in a plastic bag that had become filled with sand, causing the animal to drown or suffocate.

The impact of plastic entanglement on marine life is devastating, and it is essential to address this issue through individual and organizational efforts to protect marine animals and reduce plastic pollution.

Plastic debris accumulates pollutants, which are absorbed by marine life

Plastic pollution is a pressing issue that poses a grave threat to marine life and ecosystems. The accumulation of plastic debris in the ocean has formed vast garbage patches, with the Great Pacific Garbage Patch being the largest. This plastic debris acts as a breeding ground for pollutants, which further exacerbates the detrimental effects on marine organisms.

Plastic, due to its durable nature, persists in the environment for extended periods, providing a surface for pollutants to attach. These pollutants include toxic chemicals, oils, and other contaminants. As plastic breaks down into microplastics, these particles become vehicles for the toxins, facilitating their absorption into the bodies and tissues of marine creatures. The toxins can cause developmental, neurological, reproductive, and immune disorders, impacting not only marine life but also human health through the consumption of seafood.

The ingestion of plastic by marine animals has devastating consequences. Sea turtles, for example, often mistake plastic bags for jellyfish, their favourite food, leading to intestinal blockages and starvation. Plastic debris can also entangle marine creatures, causing injuries, infections, and drowning. The impact of plastic pollution extends beyond the directly affected animals, as toxins enter the food chain, ultimately reaching humans.

The extent of plastic pollution in the oceans is staggering, with an estimated 100 million metric tons of plastic polluting our seas. This pollution affects almost 1,000 species of marine animals, and the number of deaths is challenging to determine due to the majority of unobserved incidents. However, it is estimated that at least 100,000 marine animals perish from plastic pollution annually, with this figure likely being an underestimate.

The impact of plastic pollution on marine life is undeniable, and it is crucial to address this global crisis. Reducing plastic waste, improving waste management practices, and preventing plastic from entering rivers and oceans are essential steps toward mitigating the devastating effects of plastic pollution on marine ecosystems and the planet's inhabitants.

Plastic waste is estimated to kill 100,000 marine animals each year

Plastic pollution in the ocean is having a devastating impact on marine life. It is estimated that plastic waste kills 100,000 marine animals each year, but this number is likely an underestimate. The true extent of plastic pollution on marine life is difficult to determine, as the majority of deaths go unobserved. However, it is clear that plastic pollution is a significant threat to marine ecosystems.

Plastic pollution can affect marine animals in several ways, primarily through ingestion or entanglement. Sea turtles, for example, often mistake plastic bags for jellyfish and eat them. Once ingested, plastic blocks their digestive systems, leading to starvation. Similarly, whales have been found with large quantities of plastic in their digestive tracts, causing fatal inflammation. Plastic fishing nets and other debris can also entangle marine animals, leading to suffocation or drowning. Even if they can move while entangled, their prospects are not good. The plastic can cut into their skin, causing severe injuries that may become infected and fatal.

Plastic pollution has impacted at least 267 species worldwide, including 86% of all sea turtle species, 44% of all seabird species, and 43% of all marine mammal species. It is estimated that 56% of the planet's whale, dolphin, and porpoise species have consumed plastic. In addition, almost 1,000 species of marine animals are impacted by ocean pollution, and there are over 500 locations recorded as dead zones where marine life cannot exist due to pollution.

The plastic waste that ends up in the ocean often originates from land. It washes out to sea from beaches, streets, and highways and flows through storm drains into streams and rivers. Eighty percent of the plastic debris in the ocean comes from land-based sources. The items we throw away and the chemicals we produce will make their way to the sea even if they are discarded far from the coastline. For example, a small item of debris dropped near California can travel across to Japan and eventually get sucked up by garbage patch vortexes. These garbage patches can be massive, with the Great Pacific Garbage Patch spanning an area twice the size of Texas.

The impact of plastic pollution on marine life is severe and widespread. It is essential to address this issue through individual and collective action to protect marine life and preserve the health of our oceans.

Plastic pollution impacts almost 1,000 species of marine animals

Plastic pollution is a pressing issue that poses a significant threat to marine life. It is estimated that plastic pollution impacts almost 1,000 species of marine animals, with far-reaching consequences for both the environment and human activities that depend on healthy marine ecosystems.

Marine animals face a dual threat from plastic pollution through ingestion and entanglement. When marine animals mistake plastic waste for food, it can lead to fatal blockages in their digestive systems, causing starvation. This issue is particularly prevalent among sea turtles, which often consume plastic bags, mistaking them for jellyfish. Additionally, discarded fishing nets and ropes made of plastic can entangle marine creatures, restricting their movement, causing injuries, and increasing their vulnerability to predators and infections.

The impact of plastic pollution on marine life is not limited to immediate physical harm. Plastics can carry and release toxic chemicals, which accumulate in the fatty tissues of animals that ingest them. These toxins can then biomagnify up the food chain, affecting apex predators such as orcas and great white sharks, and ultimately reaching humans through seafood consumption.

The magnitude of plastic pollution in the oceans is staggering. It is estimated that up to 13 million metric tons of plastic enter the ocean each year, with plastic debris floating over the ocean surface totaling five trillion pieces and weighing over 260,000 tons. This plastic pollution has led to the creation of vast garbage patches, such as the Great Pacific Garbage Patch, which is twice the size of Texas.

The impact of plastic pollution extends beyond the nearly 1,000 species directly affected. Marine ecosystems are suffering irreparable damage, with over 100 million marine animals lost annually and the decay of ocean ecosystems. This has severe economic implications, particularly for developing countries and islands that rely heavily on marine resources for food and livelihood.

Addressing plastic pollution requires collective efforts from individuals, organizations, and governments. While the task may seem daunting, taking action through conservation initiatives, responsible waste management, and reduced plastic consumption can help mitigate the impact of plastic pollution on marine life and work towards restoring the health of our oceans.
