Plastic bags are used everyday to carry home shopping. When they are finished with they end up as rubbish in our bins. Also some rubbish is carelessly dumped by road sides or in fields or beaches. This causes bags left on beaches to end up in the sea. Plastic bags cause marine pollution. Plastic bags are made from oil and take hundreds of years to decompose.When plastic bags end up in the sea, ocean currents carry them to feeding grounds. Plastic bags look like jellyfish in the water which is the main food for leather back turtles. Turtles eat the plastic bags because they think it is there food which can cause their stomach to be blocked.
