Here's a very interesting article about how we have made Earth's oceans 30% more acidic than it was in pre-industrial times. This has happened because of all the carbon dioxide that we have put in the atmosphere and the ocean has absorbed. We're running a giant chemistry experiment on ocean life and how it adapts (or doesn't) to acidifying conditions.
Why should we care? The ocean provides 90+% of our oxygen and a great deal of our food supply. If you like breathing and eating, then this is something you should be concerned about.
