Why is that asinine? If these animals like warmth and/or warmth increases their fertility, then warmth (from whatever source) can conceivably help them thrive. Right? I don't understand your objection.
An idiotic statement. Have a friend relax the tourniquet around your neck and allow some hemoglobin to flow to your brain stem.
It's a matter of relative population levels. The numbers are greater now than they were, because animals that would have frozen before the pipeline went in now survive.
Are such things really that difficult to understand in liberal la-la land?
