A new report says plastics are responsible for $13 billion in damage to the oceans and the undersea environment. The findings were announced recently at a United Nations conference. 1.

Plastic thrown away carelessly makes its way into rivers and other waterways2.After a while, it collects in the sea. And plastic never goes away. Plastic is not biodegradable—destroyed by bacteria or natural processes. Instead, it just breaks up into smaller pieces over time. The oceans contain a lot of chemicals and other pollutants.3.That means harmful material may get into our food supply.

4.Human beings cause pollution and they can take steps to stop it. They can use fewer single use product containers and throw plastics away correctly. Plastic recycling programs also works—where old bottles and other plastics are collected, broken down and used to make new products. We could reuse bottles in our households many times if we wish to, rather than end it after the first use. We could, when we get rid of that plastic, recycle it and reuse it, which replaces the need for raw materials.

The report also calls on companies to improve methods for using plastics. 5.And it calls for information about the way plastic is thrown out or removed from use. By putting a new value on plastic, industry has a special reason to clean up the environment.
