8.3 Billion Tons of Plastic.

Humans have made at least 8.3 billion tons of plastic, and most of it is discarded into the natural environment. Only 9% has been recycled, according to Great Britain's Royal Statistical Society.

National Geographic reports that most of the plastic pollution can be attributed to plastic packaging.
