I like to describe the aliens that attack you in factorio as environmentalists.
Pollution actually makes the bugs stronger. Maybe they like pollution and want to go eat it all up.
They get stronger because they mutate to fight back
I never meant evolution, or to spark a debate about it. They fucking get stronger the more poison there is, maybe something whacky happens to them
Thatβs 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 doesnβt make a species better fighters.
