Oceans and coasts

Facing threats from plastic pollution to over-fishing, oceans need our help more than ever

From biodiversity and food supply to the livelihoods of millions, so much depends on our oceans.

We believe that protecting this precious resource is everyone's responsibility.

Earthwatchers are filling knowledge gaps on key marine species and the effects of climate change. The data we collect will help protect our oceans for future generations to enjoy.
