The ocean's tipping point

Interesting article in today's Washington Post linked above about extinction of fish and marine animals. I learned some things I didn't know, so check it out, you might too.

Like this:

In the past 300 years, researchers have documented the global extinction of just 21 marine species -- and 16 have occurred since 1972.

Since the 1700s, another 112 species have died out in particular regions, and that trend, too, has accelerated since the mid-1960s: Nearly two dozen shark species are close to disappearing, according to the World Conservation Union, an international coalition of government and advocacy groups.
