I think a parephrase of Martin Niemöller 1946 statement is appropriate today in light of the ecological disaster taking place in the Gulf of Mexico.
"THEY FIRST destroyed the oceans,
and I didn't speak up because I wasn't an environmentalist,
THEN THEY poisoned the atmosphere,
and I didn't speak up because I did not understand the danger involved
THEN THEY decimated the forests,
and I didn't speak up because they were far away and out of sight
THEN we started dying, the lack of food, water and and diseases caused by pollution.
and by that time no one was left to speak up."
