It's exactly the same type of grub-steaking that existed in this nation under the manifest destiny period that only ended in the last quarter of the 20th century and was only stopped by an act of Congress.
If you consider the devastation caused by the gold rushes, the timber booms, sod busting, the fish-wheels, the hydro projects, King Coal, and just simply the American Culture of Gimme Gimme Now it's easy to say that if it wasn't for Teddy Roosevelt, there wouldn't be a shred left today. Even still every year lobbyists hired by the big trusts spend millions trying to get Congress to open up our Nat'l parks for drilling, mining, & clearcutting.
Even my own dad used to use old dirty motor oil as a brush killer and worn out tires as bonfire starters just as his old man taught him.
We're still waiting for the final butcher's bill Big Oil is going to leave us with.
