Tens of thousands of whales, birds, seals and turtles are killed every year from plastic bag litter in the marine environment as they often mistake plastic bags for food such as jellyfish. … Plastic bags, once ingested, cannot be digested or passed by an animal so it stays in the gut.
How is plastic harmful for animals?
Animals can starve when they ingest too much plastic that they can’t digest. When animals ingest plastic waste, it can block their digestive tracts. As a result, they starve. Toxic chemicals in plastic can harm animals’ health—and people can ingest these chemicals as they make their way up the food chain.
Why are plastic bags harmful to wildlife and marine life?
When plastic bags end up in our oceans, animals (including seals, dolphins and seabirds) can get tangled up in them. An animal with a plastic bag around its neck will have trouble moving through the water, catching its prey or feeding, and escaping predators.
How do plastic impact animals and the environment?
In the case where the limbs of animals are trapped, it makes them less agile and more vulnerable to predators, competitors, and environmental stress. If they manage to eat the plastic, it can also cause intestinal blockages and can become fatal for that animal.
How does plastic affect coral reefs?
In areas polluted by plastic, corals are more susceptible to disease development. Contact between debris and corals could cause physical injury to coral tissues and thus promote their infection by bacteria present on plastic debris. This study highlights the importance of combating plastic pollution in the oceans.
How many animals are affected by plastic?
More than 1,200 species are impacted by plastic, through ingestion or entanglement—both of which can sicken or even kill them. Birds, fish, turtles, dolphins, sharks and even whales can be poisoned or trapped by plastic waste.
How are plastic bags harming the environment?
Plastic bags are difficult and costly to recycle and most end up on landfill sites where they take around 300 years to photodegrade. They break down into tiny toxic particles that contaminate the soil and waterways and enter the food chain when animals accidentally ingest them.
What animals are most affected by plastic pollution?
Here are some of the marine species most deeply impacted by plastic pollution.
- Sea Turtles. Like many other marine animals, sea turtles mistake plastic waste for a viable food source, sometimes causing blockages in their digestive system. …
- Seals and Sea Lions. …
- Seabirds. …
- Fish. …
- Whales and Dolphins.
What can happen if an animal eats a traditional plastic bag?
Jagged plastic can get stuck in their throats, causing them to suffocate or prevent them from regurgitating to feed their chicks. Plastic can accumulate in animals’ stomachs, making them feel full, stopping them from eating and resulting in starvation.
How does plastic bags affect marine life?
Impacts on marine ecosystems
Marine wildlife such as seabirds, whales, fish and turtles mistake plastic waste for prey; most then die of starvation as their stomachs become filled with plastic. They also suffer from lacerations, infections, reduced ability to swim, and internal injuries.
How does plastic waste affect the Great Barrier Reef?
Marine debris is a major threat to the health of the Great Barrier Reef and kills marine life such as turtles, dugongs, dolphins and seabirds. … More than 80 per cent of marine debris found in the Reef is plastic, which can break up into smaller pieces and travel vast distances, increasing the risk of impacts.
How does plastic pollution affect marine plants?
500. marine species are known to be affected by plastic pollution. … To make matters worse, the durable nature of plastic means that this material does not biodegrade in the ocean. It simply breaks up into smaller and smaller pieces, lingering in the marine environment for centuries.
