One of the worst things that should be brought to attention of environmentalists is that the wet prairies up north are being tiled annd drained, and that virgin prairie is being tilled under for corn. Land enrolled in CRP is being tilled under as well, because the price of corn makes up for the fine you have to pay for failing to agree to the terms. South Louisiana used to be almost 2 million acres of prairie and got converted to ag, now only a few hundred acres remain. Doesn't seem like a big deal, but when you think of this happening up north, that is the Duck Factory being plowed under
