The second form of plastic that causes tremendous damage is plastic resin pellets. These plastics are used for packaging. These pellets have been found in concentrations up to 3,500 per square kilometer in the Atlantic Ocean and up to 34,000 pellets per square kilometer in the Pacific Ocean. The main polluter in the ocean is cargo waste from merchant shipping. They are responsible for 12,348,000,000 pounds of trash per year.
Plastic is very harmful for marine life.
Plastic causes entanglement and death for sea animals. Turtles mistake plastic bags for jellyfish. This substance lines their stomachs and enables them from absorbing any of the food they consume, which causes them to starve to death. Another main cause of water pollution is rain run off. This is responsible for half of the nations water pollution.
