Plastic pollution is a global crisis that has reached every corner of the natural world, from the deepest point of the Mariana Trench to the top of Mount Everest. The ocean is perhaps the most vulnerable environment to plastic waste. Once plastic enters the sea, it can move freely, wreaking havoc on marine ecosystems and the animals that inhabit them. Marine animals of all sizes, from small finches to blue whales, are dying from ingesting plastic or getting entangled in it. It is estimated that marine plastics contribute to the death of more than 100,000 marine mammals every year.

What You'll Learn
Plastic ingestion causes starvation, intestinal injury and death
Marine animals are ingesting plastic at alarming rates, with plastic waste found in the stomachs of seabirds, whales, dolphins, fish, marine mammals, and sea turtles. This ingestion of plastic is causing starvation, intestinal injury, and death in these creatures.
Starvation occurs when plastic fills the stomach, leading to a false sense of fullness and a subsequent loss of appetite. This was observed in sea turtles, where plastic bags and sheeting in their stomachs made them feel full, reducing their urge to feed and resulting in malnutrition. Similarly, albatross chicks that ingested plastic had lower weights as the plastic prevented them from consuming a full meal.
Intestinal injuries and internal bleeding can occur when sharp or rough plastic creates cuts in the digestive system. Plastic can also obstruct digestion, leading to intestinal blockage and the risk of infection. In some cases, a single piece of ingested plastic has been enough to cause death, as seen in a pygmy sperm whale found with a plastic bag in its stomach.
The impact of plastic ingestion on marine life is severe, with an estimated 100,000 marine mammals killed annually due to plastic pollution. Sea turtles, in particular, are highly affected, with half of sea turtles worldwide having ingested plastic, leading to increased risks of starvation, internal injuries, and death.
The consequences of plastic ingestion extend beyond the individual animals affected. Biomagnification occurs when toxins from ingested plastic accumulate in the fatty tissues of animals, passing up the food chain and resulting in higher toxin concentrations in apex predators such as great white sharks and orcas.
The vast reach of plastic pollution in our oceans underscores the urgent need for action to address this crisis. With marine animals suffering from starvation, intestinal injuries, and death due to plastic ingestion, it is imperative that we take steps to reduce, recycle, and properly dispose of plastic waste to protect these vulnerable creatures and their ecosystems.

Marine animals get entangled in plastic debris and fishing gear
Marine animals face a significant threat from plastic pollution in the ocean, which has reached every corner of the natural world. Plastic debris and fishing gear entanglement is one of the primary ways in which marine animals are harmed by plastic pollution.
Plastic pollution in the ocean has increased by 40% in the last decade, and entanglement is a significant contributor to this. Marine animals, such as whales, dolphins, seals, sea lions, and sea turtles, frequently become entangled in plastic debris and fishing gear as they swim or while resting on beaches. This entanglement can lead to drowning, starvation, physical trauma, and infections. Large whales, for example, can pull gear off the ocean floor but are still at risk of exhaustion and infection. Smaller animals, like turtles, seals, and dolphins, may drown immediately if entangled in large or heavy gear.
The impact of plastic pollution on marine animals is not limited to physical harm. Marine debris can also affect their ability to capture and digest food, sense hunger, escape predators, and reproduce. It can also decrease their overall health and impair their movement. Even if entangled animals can move, their chances of survival are slim. They may be unable to escape from vessels, increasing the risk of vessel strikes.
Plastic pollution in the ocean comes from various sources, including single-use plastic items, fishing gear, and microplastics. Single-use plastics, such as plastic bags, bottles, and takeout containers, are a significant contributor to marine debris. Fishing gear, both commercial and recreational, can be lost or abandoned, becoming deadly traps for unsuspecting marine creatures. Microplastics, tiny plastic particles, can also contaminate the ocean and be ingested by marine animals, leading to toxic contamination.
The problem of plastic pollution in the ocean is a pressing issue that requires urgent attention. It is estimated that up to 13 million tons of plastic waste enter the ocean each year, threatening marine ecosystems and the people who depend on them. Efforts to address this issue include policy changes, recycling initiatives, and community cleanups. It is crucial to recognize that plastic pollution is a human-created problem that requires human-led solutions to protect and restore marine habitats and the animals that call them home.

Plastic affects the reproduction rates of sea turtles
Plastic is devastating to nature. The ocean is perhaps the most vulnerable environment when it comes to plastic waste. Once plastic enters the sea, it can move anywhere, and it takes hundreds, if not thousands, of years to degrade.
Sea turtles are affected by plastic at every stage of their life. They crawl through plastic on their way to the ocean as hatchlings, swim through it while migrating, confuse it for jellyfish (one of their favourite foods), and then crawl back through it as adults.
Plastic waste kills up to a million seabirds a year, and sea turtles are similarly affected. When turtles ingest plastic, it takes up room in their stomachs, sometimes causing starvation. A recent study found that sea turtles that ingest just 14 pieces of plastic have an increased risk of death. The young are especially at risk because they are not as selective as adults about what they eat and tend to drift with currents, just as plastic does.
Plastic waste on beaches is also affecting turtles' reproduction rates by altering the temperatures of the sand where incubation occurs. Additionally, tiny bits of plastic in the sand can affect nests and hatchlings.
Plastic pollution in the ocean is a massive problem that is impacting sea turtles and many other marine species. It is estimated that up to 13 million metric tons of plastic end up in the ocean each year, threatening marine ecosystems and the people who depend on them.

Microplastics are ingested by molluscs and contaminate the food chain
Plastic waste in the ocean is a significant environmental problem, with plastic taking hundreds, potentially thousands of years to degrade. Marine species are affected in a variety of ways, including entanglement, injury, ingestion, and toxic contamination.
One of the ways plastic enters the marine food chain is through molluscs, such as mussels and oysters, which filter seawater to feed. In doing so, they also take in microplastics, which are pieces of plastic debris under five millimetres in length. These microplastics can be ingested by molluscs, contaminating them and entering the food chain. A recent study found that 100% of mussels sampled from UK waters contained microplastic pieces.
As molluscs are consumed by other marine species, the microplastics are passed on, accumulating in the food chain. This process is known as biomagnification, and it means that the higher up the food chain you go, the greater the concentration of toxins. This poses a threat not only to marine life but also to human health, as contaminated seafood is a significant source of microplastics in the human diet.
The dangers of ingesting microplastics include the release of chemical substances, including organic and inorganic compounds, as well as additives used in the plastic manufacturing process. While the full extent of the health impacts is not yet known, studies indicate that microplastics can increase the likelihood of heart attack, stroke, and death.
The problem of plastic pollution is widespread and urgent action is required to address it. This includes reducing plastic waste, improving waste management, and supporting policies that aim to eliminate plastic pollution and promote sustainable alternatives.

Plastic pollution is deadly to marine wildlife
Plastic pollution is having a devastating impact on marine wildlife, threatening ecosystems and the people who depend on them. With billions of pounds of plastic in the oceans, no area is unaffected, and the problem is growing into a crisis.
Another way plastic kills marine wildlife is through entanglement. Marine mammals, birds, and other creatures can get entangled in plastic-based fishing gear, nets, or discarded fishing lines, leading to loss of limbs, wounds, suffocation, and drowning. Even if they can move, their prospects are not good, as the plastic can cut deep into their skin, leaving them vulnerable to deadly infections.
Plastic also affects marine wildlife through toxic contamination. Microplastics can contain up to one million times more toxic chemicals than the water around them. These toxins can build up in the fatty tissues of animals, leading to a condition called biomagnification, where the concentration of toxins increases as you move up the food chain.
The durability of plastic means it can persist in the environment for hundreds, if not thousands, of years. This makes retrieving plastics from the ocean extremely difficult, as they break down into smaller and smaller pieces. The size of the plastic pieces can adversely affect different species in different ways and on different timescales.
The impact of plastic pollution on marine wildlife is widespread and severe, affecting vulnerable hatchlings to great white sharks and blue whales. It is essential to address this urgent problem to protect marine ecosystems and the planet's health.

Frequently asked questions
Plastic in the ocean has a direct and deadly effect on wildlife. It affects creatures large and small, from seabirds, whales, and dolphins to tiny seahorses that live in coral reefs. Marine animals often mistake plastic for food, which can cause intestinal injury and death. It can also cause entanglement and injury, toxic contamination, and starvation.
Plastic enters the ocean through discarded fishing gear, single-use packaging, consumer goods, and microplastic fibers in clothing. It is also produced by companies that use fracked gas to create plastic.
Sea turtles often mistake plastic for prey, which can cause intestinal injury and death, or starvation. Plastic can also cause sea turtles to become positively buoyant and unable to dive, making them more susceptible to predators or boats.
To reduce the impact of plastic on sea animals, we can support organizations working to reduce plastic pollution, recycle and reuse products, and participate in beach or community cleanups. We can also support campaigns that urge companies to cut down on single-use plastic production and pressure governments to regulate plastics as pollutants.
