I understand where you are coming from. But I don't agree with it. In a few areas it won't impact much. But overall I can think of hundreds of scenarios that aren't going to do the ecosystems any favors. Crappy water quality starts somewhere. The higher in the drainage it starts the more it impacts. Things flow downhill. A green light to go back to more destructive land uses is only going to make things worse.
This is nothing more than political games. Optimistically we can hope the next regime is more ecologically sound. There's always hope...
