The De-Evolution of the Earth's Oceans

A couple of posts back, I rather flippantly discussed the effects of domoic acid poisoning on a local pelican. There's a grimly fascinating and informative series over at the LAT that gets into the details of observed phenomena, attributed to human activity, that indicate the oceans of Earth are returning to a prehistoric state, a state where algae and bacteria rule, and higher forms of sea life such as fish and sea mammals are faced with bleak chances of survival. My usual sarcasm fails me. Please read the series here. (One time registration may be required).
