Marine animals are suffering from plastic pollution in the ocean. It is difficult to know the exact number of marine animals that are killed by plastic each year, but estimates range from 100,000 to 100 million. The majority of marine animal deaths are unobserved, so it is challenging to estimate accurately. However, scientists have found that the number of animals affected by plastic pollution is vast.
| Characteristics | Values |
|---|---|
| Number of marine animals killed by plastic each year | 100,000-1,000,000 |
| Number of marine animals killed by plastic ingestion each year | 100,000-1,000,000 |
| Number of marine animals killed by plastic entanglement each year | 100,000-1,000,000 |
| Number of sea turtles killed by plastic each year | 50% of sea turtles are impacted by plastic |
| Number of marine mammal species that have eaten or been entangled in plastic | 81 out of 123 |
| Number of sea turtle species impacted by plastic | 7 out of 7 |
What You'll Learn
Plastic ingestion
It is difficult to know the exact number of marine animals that die from plastic pollution each year. Many deaths go unrecorded and unobserved, and it is challenging to determine the cause of death. However, it is estimated that at least 100,000 marine animals die from plastic ingestion or entanglement annually. This number is likely an underestimate, as it only accounts for a few species.
Sea turtles are particularly vulnerable to plastic ingestion, with all seven species affected. Plastic bags resemble jellyfish, an essential part of their diet, and this leads to turtles ingesting plastic. The plastic clogs their digestive systems, causing fatal blockages.
While the exact number of deaths due to plastic ingestion is challenging to determine, it is clear that this issue is having a significant impact on marine life. More research is needed to fully understand the extent of the problem and develop effective solutions to reduce plastic pollution in our oceans.

Entanglement in plastic-based fishing gear
It is challenging to estimate the exact number of marine animals that die from plastic pollution each year. Many deaths go unrecorded, and it is difficult to determine the cause of death. However, scientists have found that the number of animals affected by plastic pollution is vast. It is estimated that at least 100,000 marine animals die from plastic pollution every year, with some estimates reaching over 1 million. The majority of these deaths are seabirds, with marine mammals accounting for about 100,000 deaths. These numbers are likely underestimates, as they only account for a few species.
One of the two primary ways that marine animals encounter fatal debris is through entanglement in plastic-based fishing gear. This type of gear includes items such as fishing nets, which can entangle marine mammals and sea turtles, causing inflammation of their abdominal tissues and eventual death. All seven species of sea turtles are affected by plastic pollution, with 50% of sea turtles impacted by plastics, ingesting them, and dying through their digestive systems becoming clogged.
The impact of plastic pollution on marine life is severe and often underestimated. More research is needed to determine the full extent of the problem. However, it is clear that entanglement in plastic-based fishing gear is a significant issue that is contributing to the deaths of many marine animals.
To reduce the number of marine animal deaths caused by plastic pollution, it is essential to address the issue of plastic waste in our oceans. This includes reducing the use of single-use plastics, properly disposing of plastic waste, and implementing measures to prevent plastic from entering our oceans in the first place. By taking action to reduce plastic pollution, we can help protect marine life and ensure the health of our oceans for future generations.

Plastic production emissions
It is difficult to know exactly how many marine animals are killed by plastic pollution each year. Many deaths go completely unrecorded, and the impact of plastic pollution is often underestimated. However, it is estimated that at least 100,000 marine animals die from plastic pollution annually, with some estimates placing the figure at over 1 million. The majority of these deaths are seabirds, although mammals are more visible in the media. All seven species of sea turtle are affected by plastic pollution, with 50% of sea turtles impacted by plastics, often ingesting them and dying when their digestive systems become clogged.
These figures only account for a few species, and only for the direct impact of plastic debris in the ocean. If other factors, such as emissions from plastic production or transport, were taken into account, the toll would likely be much higher.

Plastic transport emissions
It is difficult to know the exact number of marine animals that are killed by plastic pollution each year. This is because many deaths go unrecorded and unobserved, and it is challenging to determine the cause of death of marine animals. However, scientists have estimated that at least 100,000 marine animals die from plastic pollution annually. This number is likely an underestimate, as it only accounts for a few species.
The majority of animals that die are seabirds, with mammals often being more visible in the media but only accounting for about 100,000 deaths. Sea turtles are also heavily impacted by plastic pollution, with all seven species affected. It is believed that 50% of sea turtles are impacted by plastics, ingesting them and dying through their digestive systems becoming clogged.
The impact of plastic pollution on marine life is often underestimated, and the number of animals affected is vast. The true toll of plastic pollution on marine life would likely be much higher if other factors such as emissions from plastic production or transport were taken into account.

Plastic pollution in the ocean
The impact of plastic pollution extends across a diverse range of marine species. Sea turtles are particularly vulnerable, with all seven species affected by plastic debris. It is estimated that 50% of sea turtles are impacted by plastics, often mistaking plastic bags for jellyfish, a crucial part of their diet. This results in fatal intestinal blockages or inflammation of abdominal tissues due to the ingestion of indigestible plastic.
Marine mammals also face grave risks from plastic pollution. Out of 123 marine mammal species, 81 have been documented to ingest or become entangled in plastic. The presence of plastic in their digestive systems can lead to fatal inflammation of abdominal tissues. Sadly, the actual number of affected mammals is likely much higher, as many deaths may go unnoticed or unreported.
The true extent of plastic pollution's impact on marine life remains unknown, and further research is needed. However, it is evident that plastic debris in the ocean poses a significant threat to a wide array of marine species, including sea turtles and mammals. The issue underscores the urgent need for measures to reduce plastic waste and protect vulnerable marine ecosystems.

Frequently asked questions
It is hard to know the exact number of marine animals that are killed by plastic each year, but some estimates put the figure at 100,000, while others say it could be as high as 1 million or even 100 million.
Marine animals can die from ingesting plastic or becoming entangled in plastic-based fishing gear.
Seabirds and sea turtles are among the most affected by plastic pollution. Eight out of 123 marine mammal species are known to have eaten or been entangled in plastic, and all seven sea turtle species are affected.
Reducing plastic pollution in the ocean is key to reducing the number of marine animal deaths. This can be achieved through measures such as reducing plastic waste, improving waste management practices, and implementing policies to reduce plastic production and consumption.
