> There's a reason for the word "tragedy" in the phrase, "the tragedy of the commons"

Small but important clarification: as Garrett Hardin later said, he should have called it the tragedy of the unregulated commons. The problem is not the fact that the ocean doesn't have a private owner but rather that the legal framework does not presently cover its responsible access and use.

True, so let's be even more exact: "presently" is the wrong tense; present acidification and warming are consequences of actions taken over the last several decades.
