How does marine pollution effect Leatherback turtles?

Where do your plastic bags end up when they are out of use? Have you ever wondered what plastic are made from? They're made from oil, a natural resource, which takes hundreds of years to decompose (break down and disintagrate). The plastic bags cause problems for marine life (sea life/creatures) especially leatherback turtles.
By 2030 Leatherback turtles will be extinct because of all the marine pollution. Marine pollution comes from the people who don't care and the people who dump all of the rubbish on the beaches. Leatherback turtles eat the plastic bags because they think it is their source of food. Plastic bags look like jellyfish in the water therefore the turtles eat them and starve to death. When Leatherback turtles eat the plastic bags their stomach becomes blocked and they starve to death.
