How does pollution affects Leatherback turtles


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 jelly fish 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 inn the turtles stomach becomes blocked .The turtles starve to death.Consequently by 2030 leather back turtles will be extinct.

Plastic bags are used everyday in order to carry home shopping .When they are finished with they end up in the sea as rubbish in our bins. Some rubbish is carelessly dumped on road sides in fields or on beaches however rubbish is taken up to landfill sites . Bags left on beaches end up in the sea which causes marine pollution . Plastic bags are made from oil . This causes plastic bags to take hundreds of years to decompose .
