How does poulution affect Leatherback turtles?

Plastic bags are used every day to carry home shopping so that when they are finished with them they end up as rubbish in our bins. Some rubbish is carelessly dumped by roadsides in fields or on beaches however some rubbish is taken to landfill sites. Bags left on beaches end up in the sea which causes plastic bags to cause marine pollution. Plastic bags are made from oil. This causes plastic bags to take hundreds of years to decompose.
Plastic bags left on the 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 jelly fish in the water which are the main source of food for Leather back turtles. Turtles eat the plastic because they think they are their food which results in the turtles stomach becoming blocked. Turtles starve to death. Consequently by 2030 Leatherback turtles will be extinct.
