Chances are the painted snipe (or whatever) was going extinct anyway. Most species do.
I am quite green by inclination (I have a rural property and plant 200+ trees a year on it) but I can't help thinking that if a spider (or newt, or butterfly) has such a restricted range that a by-pass will wipe it out, well, we are just helping nature on a little bit.
The thing we humans have to make sure of though, is that we don't become like that spider (or newt, or butterfly). Keeping the planet habitable is in all of our interests. Which is why creating this legal fiction of a corporation that has the rights of people but none of the needs, is just plain insane.
