Plastic is a major threat to sea turtles, impacting them at every stage of their life cycle. From hatchlings crawling to the ocean to adults migrating, sea turtles encounter plastic waste that can cause them harm. Plastic pollution affects sea turtles in two main ways: ingestion and entanglement. Sea turtles can mistake plastic for food, such as jellyfish, leading to blockages in their digestive system and eventual death. They also risk entanglement in plastic waste, such as discarded fishing gear, which can hinder their ability to swim, surface for air, or feed, and even lead to drowning. With sea turtle populations already decreasing, addressing plastic pollution is crucial to ensuring the survival of these ancient mariners.

What You'll Learn
Turtles eat plastic that resembles food
Sea turtles are among the many marine creatures that ingest plastic, mistaking it for their natural food. This is because a floating plastic bag can resemble a jellyfish, algae, or other species that make up a large component of the sea turtles' diets. All seven species of sea turtles are at risk of ingesting plastic, including the carnivorous loggerhead and the mainly plant-eating green turtle. Research suggests that 52% of the world's turtles have eaten plastic waste.
Turtles in the eastern Mediterranean displayed strong diet-related selectivity towards certain types (sheet and thread-like), colours (black, clear and green), and shapes (linear items were strongly preferred) of plastic when compared to the environmental baseline of plastic beach debris. This indicates that turtles do not simply mistake plastic for food but are actively seeking out and consuming certain types of plastic that resemble their natural diet.
The ingestion of plastic can cause physical damage to turtles' intestines, lead to blockages, or trick the turtles into feeling full when they are not, leading to sickness or death. Additionally, consuming plastic can make turtles unnaturally buoyant, which can stunt their growth and lead to slow reproduction rates.
Turtles can also ingest plastic indirectly when tiny bits of plastic are consumed by their prey, such as fish or other animals, which are then eaten by the turtles. This means that even when turtles do not mistake plastic for food, they can still inadvertently consume microplastics that have entered the food chain.

Plastic ingestion causes intestinal blockages
Plastic is a major threat to sea turtles. Research suggests that 52% of the world's turtles have eaten plastic waste. Sea turtles ingest plastic by mistaking it for their natural food, such as mistaking a plastic bag for a jellyfish, or by accidentally eating plastic that is present among their natural food, such as a plastic straw.
Plastic bags are petroleum-based and do not biodegrade. Sea turtles and other marine creatures mistake plastics and other garbage for food, causing blockages within their digestive system and eventual death.
Even if they survive, consuming plastic can make turtles unnaturally buoyant, which can stunt their growth and lead to slow reproduction rates. Plastic ingestion can also cause sharp plastics to puncture internal organs, and bags can cause intestinal blockages.

Turtles get entangled in plastic waste
Plastic waste is a major threat to sea turtles. Sea turtles come into contact with plastic debris at various stages of their life cycles and in a range of different habitats, both near the coast and in the open ocean.
Sea turtles often get entangled in plastic waste, such as discarded fishing gear, also known as "ghost nets" or "ghost gear," and other debris while migrating, feeding, or nesting. This entanglement can lead to injuries, hinder their ability to swim, surface for air, or feed, and, in severe cases, cause drowning and death. Turtles can also get entangled in plastic waste on land, such as car tires, which can trap them and make it difficult to reach the ocean.
The presence of plastic waste on beaches is a significant concern for baby sea turtles. As they hatch from their eggs, they must dig their way out of the sand and race towards the ocean, dodging predators. Plastic debris on beaches can create obstacles and entangle the hatchlings, preventing them from reaching the water safely.
Additionally, plastic waste can have indirect effects on sea turtles by impacting their nesting habits. Female sea turtles are particular about finding suitable nesting spots to lay their eggs. However, the increasing presence of plastic pollution on beaches can force them to lay their nests in suboptimal locations or expose them to additional risks as they navigate through the debris.
The entanglement in plastic waste and the resulting inability to move freely or access essential resources can have severe consequences for the health and survival of sea turtles, contributing to the decline in their populations.

Plastic affects turtles at every life stage
Once in the ocean, turtles swim through plastic waste while migrating and can confuse plastic for their natural food, such as jellyfish, due to its similar appearance and smell. This ingestion of plastic causes internal blockages and physical damage to their intestines, leading to sickness and death. It can also make them unnaturally buoyant, hindering their ability to swim and escape predators.
Adult turtles continue to face the threat of plastic entanglement and ingestion. They can become entangled in discarded fishing gear, also known as "ghost nets", which can lead to injuries, drowning, or difficulty feeding and surfacing for air. The presence of plastic on nesting beaches also poses a challenge for adult turtles as they crawl through the debris to find a suitable spot to nest.
Additionally, plastic pollution has broader impacts on the turtle population. It affects their habitats and food sources, with microplastics entering the oceans from various human activities. The ingestion of plastic by turtles can also introduce toxic substances into their digestive systems, further endangering their health. Overall, plastic pollution has contributed to the decline in global turtle populations, with all seven species of sea turtles impacted.

Plastic pollution stunts population growth
Plastic pollution is a major threat to sea turtles, impacting them at every stage of their life cycle and in a range of habitats. Sea turtles ingest plastic by mistaking it for their natural food, such as jellyfish, or by accidentally consuming it along with their natural food. Research suggests that more than half of all sea turtles have eaten plastic waste, with some studies showing that the carnivorous loggerhead and the mainly plant-eating green turtle were consuming plastic in alarming quantities.
The ingestion of plastic can cause physical damage to their intestines, lead to blockages, or trick turtles into feeling full when they are not, leading to sickness or even death. In addition, consuming plastic can make turtles unnaturally buoyant, which stunts their growth and leads to slower reproduction rates.
Turtles also face the risk of entanglement in plastic waste, such as discarded fishing gear, while they are migrating, feeding, or nesting. Entanglement can cause injuries, hinder their ability to swim, surface for air, or feed, and in severe cases, lead to drowning or prevent them from escaping predators.
The presence of plastic on beaches is a significant threat to baby sea turtles, as they must crawl through the debris to reach the ocean. Plastic debris on nesting beaches also affects adult sea turtles, as they have to crawl through the collected debris to find a place to nest. The decrease in global turtle population numbers in recent years has been attributed, in large part, to plastic pollution.

Frequently asked questions
Plastic affects turtles in two main ways: ingestion and entanglement. Turtles can ingest plastic by mistaking it for their natural food, such as jellyfish, or by accidentally eating plastic that is present among their food. They can also become entangled in plastic waste, such as discarded fishing gear, which can lead to injuries, hinder their ability to swim, and in severe cases, cause drowning and death.
Turtles mistake plastic for food because plastic bags look very similar to jellyfish, and fishing nets often look like tasty seaweed. Turtles are attracted to the way marine plastics smell due to the organisms that latch on to plastic debris in the ocean.
When turtles eat plastic, it can cause physical damage to their intestines, lead to blockages, or trick them into feeling full when they are not, causing them to become sick or even die. Even if they survive, consuming plastic can make turtles unnaturally buoyant, which can stunt their growth and lead to slow reproduction rates.
Plastic entanglement can lead to injuries, choking, limb loss, and drowning. It can also hinder their ability to swim, surface for air, or feed. Entanglement can also prevent turtles from escaping predators or hunting.
