According to scientist Jeremy Jackson, our oceans are in bad shape and getting worse. When he started in on "the rise of slime" it took a few minutes to figure out he wasn't talking about politics.
As an optimist, I believe it's possible to have healthy oceans in our future. But it's hard to stay optimistic after listening to Dr. Jackson. He's seen dramatic decline in coral reefs in his lifetime, and he believes things are only getting worse.
