What happens to the plastic we throw away? Only about 9 percent of it gets recycled. Most of the rest ends up in landfills, buried under layers of dirt. Experts think this plastic may take centuries to decompose, or break down.
But a lot of plastic trash never reaches landfills. Instead, it becomes litter on the street. Rain and wind carry that litter into storm drains or rivers that flow to the ocean.
When plastic waste ends up in the ocean, the results can be deadly. Last year, a dead sperm whale washed ashore in Spain. Scientists found that the whale had eaten 64 pounds of plastic, including plastic bags, fishing nets, and even a plastic drum.
It’s not just big pieces of plastic that can be dangerous, though. In the ocean, sunlight and waves break down plastic into much smaller pieces. These tiny bits are called microplastics. They contain chemicals that can harm seabirds, turtles, and fish that swallow them.
