Science Kids: Plastic and Chemical Pollution in Oceans

The video explores the significant sources of ocean pollution, including chemical waste and plastic. It highlights the history and impact of DDT, a toxic chemical once used as an insecticide, and its ongoing environmental effects. The video also discusses the problem of plastic pollution, particularly in ocean gyres like the Great Pacific Garbage Patch. Efforts to combat pollution, such as the establishment of the EPA and the Clean Water Act, are covered, along with actions individuals can take to help protect the oceans.

What is the primary difference between point source and non-point source pollution?

• Point source pollution is from multiple sources, while non-point source is from a single source.

• Point source pollution is from a single identifiable source, while non-point source is from multiple sources.

• Point source pollution is only found in oceans, while non-point source is found on land.

• Point source pollution is less harmful than non-point source pollution.
