If you think that lush verdant tangles of forest are more beautiful than clone-stamped industrial expanses stretching beyond the horizon then your bloodline is weak and will not survive the winter. ""People"" who believe in innate human dignity or anything that could be described as "inner light" are the sociological equivalent to a biter colony and should be dealt with in a similar manner (read: flamethrowers).

Minimizing pollution is ultimately crueller to the biters than maximising it. Evolutionary failures wallowing complacently in the dirt - can you imagine anything more pathetic? Let them strive for greatness! Allowing the weak to flourish is a gross betrayal of the sacred principles that underlie creation, and will not go unpunished. Encourage an arms race, however, and all will benefit in time.
