That's not how evolution works. A species evolves to get stronger in battle if the weak ones die in battle. A species evolves stronger lungs if the weak ones die of lung cancer. Dying of lung cancer doesn't make a species better fighters.
Pollution makes their species stronger; this doesn't imply an individual preference.
Idiots walking off cliffs doesn't make the survivors like cliffs; it teaches them to avoid them.
That said, evolution can be a real crap shoot, and you never know what sort of perverse effects you'll get: like us loving sugar so much we eat ourselves into diabetes.
Maybe. Or maybe they like the pollution. Maybe with better resource availability, they're able to spend more energy on growing bigger and stronger without threatening survival.
But your corporate overlords demand it, sadness isn't efficient, get back to work!
But really they did a great job with commentary. People still say "why can't we get green energy in the game?". Because that's not the point. This is raw capitalism. You're dropped on a pristine planet, destroy the environment, clear it of all natural resources. It's &meant_ to make you feel guilty. Maybe look around outside
