Envirospeak: "last intact ecosystem"
If you ever want to see how full of shjt these neo-Marxist ecoturds are, just visit the Green River shales, which are spread all over Utah, Wyoming and Colorado. You won't have to stay more than 15 minutes to get the whole picture (but it does take several hours to get there, depending on where you start). Same thing for the Athabaska tar sands.
Almost no birds will voluntarily nest there, and critters don't even like walking through these areas, because they have to spend quite a bit of time cleaning themselves...and the water to do so is very scarce in both locales.
The oil companies lose a little bit on each barrel of tar sands oil but make up for it with volume.
