We think of the oceans as being so vast that they can absorb whatever we humans throw at them or into them. For centuries sailors have tossed their garbage into the sea, and as we humans have burnt more and more fossil fuel, so the by-product of combustion, carbon dioxide, has been absorbed by the ocean turning it very mildly acidic.
