Sorry, I remain skeptical. Just because some scientist or quasi-scientist says something does not make it so, and just because something winds up in print does not make it so. Scientists haven't even discovered all species in the ocean yet, and the're going to presume to count them? If they don't know where they are, or don't know that they exist, how can they count them?

People invent, twist, or selectively quote figures all of the time in order to make their favorite point. Just watch the news or read the papers. Who knows what their reasons are? Some are ignorant. Some do it to manipulate people. Some just parrot someone else's figures without checking them out for themselves, never mind that they may be dead wrong.

As big as the earth is, I find it difficult to believe that we have lost 90% of the ocean's big fish. Don't they breed anymore?

Sorry, I don't buy it.
