Things have gotten so bad with the human predilection for dumping plastic in the seas that, by the latest predictions, there are now more than five trillion pieces of plastic floating in our oceans.
Everyone knows that the seas are salty because, while water evaporates, the salt doesn’t. But why don’t our seas keep getting saltier?
It was decided we don’t know enough about the sea. So 2,700 scientists started the Census of Marine Life, cooperating with museums, labs and aquariums across 80 countries to learn more. 10 years later, today, they’re done.
