Nearly 269,000 tons of plastic pollution may be floating in the world’s oceans, according to a new study.
Microplastic pollution is found in varying concentrations throughout the oceans, but estimates of the global abundance and weight of floating plastics, both micro and macroplastic, lack sufficient data to support them.
To better estimate the total number of plastic particles and their weight floating in the world’s oceans, scientists from six countries contributed data from 24 expeditions collected over a six-year period from 2007-2013 across all five sub-tropical gyres, coastal Australia, Bay of Bengal, and the Mediterranean Sea…
