Ocean Acidification
Quick fact
Since the Industrial Revolution, ocean acidity has increased by about 30% (a 0.1 drop in pH), a rate of change 100 times faster than any natural variation in the last 50 million years.
Why this is interesting
The ocean has absorbed about 30% of the carbon dioxide we've emitted—but this vital service comes at a hidden cost that threatens marine life from the bottom up.
