It's the little known CO2 problem that is real, scary and already happening. It's acid oceans, brought to you by human CO2 production.
Our oceans are becomming more acid, and this problem threatens to dissolve corals and other important ocean animals, and it looks like it's already happening. YIKES! The acid levels don't sound too bad, in the language of chemistry. Just a few tenths of a pH unit--doesn't sound too bad, right?
But ask a coral and you might get a different answer. If there were such a thing, newspapers written for corals would be screaming bloody murder. Or maybe screaming "acid threatens to dissolve you and your family!" Let's think like a coral and get worried about acid oceans.
Out of sight, out of mind? Or will we rally to the cause and save our oceans from the acid plague?
