I was recently intrigued by a report on PBS about how the rising acid levels in the oceans are eating away at the coral reefs. Those mineral-rich “bones” of the sea suffer from their own version of “osteoporosis.”
And it’s not just the coral. Marine animals like scallops, oysters, and clams that rely on calcium to build their shells are having a harder time as carbon dioxide raises the acid levels of their environment. Shells are becoming thinner, and shell growth is slowing down.
