How does pollution affect turtles?


Plastic bags are used every day to carry home shopping. When they are finished with they end up as rubbish in our bins. Consequently rubbish is taken to land fill sites. Rubbish is carelessly dumped by roadsides, in fields or on beaches. As a result, bags on the beaches end up in the sea. Plastic bags are made from oil therefore they take hundreds of years to decompose (break down and disappear).
Plastic bags left on beaches end up in the sea which causes marine pollution (rubbish in the sea). Ocean currents carry plastic bags to feeding grounds. Plastic bags look like jellyfish in the water which are the main source of food for Leather back turtles. Turtles eat the plastic bags because they think they are their food which results in the turtles stomach becoming blocked. The turtles starve to death and as a result by 2030 leatherback turtles will be extinct.
