Given all of the attention we’re paying to climate change on the earth’s surface, it does seem surprising that this threat has gone relatively unnoticed so long. Most of us don’t look below the ocean’s surface. As long as we see fish in the supermarket and on our table, we don’t question where they’re coming from.
The fact is, oceans cover 71% of the earth’s surface, but we just don’t know that much about them. Only four percent of the ocean has even been explored!
But scientists are nearly unanimous in concluding that the threat excess greenhouse gas poses is real. Ocean acidification is the “sleeper” environmental issue of our time, the wet underbelly of climate change, or its evil twin.
