Maryland will begin Chesapeake clean-up and will take decades.

This is one reason why humans should take care of our environment in the first place, because if we don't, eventually it will take a long time for that affected area to recover:

But the overall picture, Batiuk said, shows a cleanup effort that is far off the pace set out in 2000. Crab populations are still below historic levels. The amount of oxygen, which fish and crabs need to live, is just 29 percent of the goal set for 2010, he said. The bay's native oysters are at just 7 percent.

Even underwater grasses, which are doing slightly better than other indicators, stand at just 42 percent of the level they're supposed to reach by 2010.

"If you draw that line out there," Batiuk said, pointing to the slow upward trend in their population, "you're at about 2040 for the grasses to come back."

I got one suggestion for the Maryland Government, don't reduce pollution, END IT.
