Rather than being nihilistic, saying nothing can be done, and continue to live pigishly or, conversely, adopting a self-loathing attitude believing that humans are parasitic vermin and that we need to voluntarily become instinct, wouldn't it be better to work towards a better future of informed and responsible living. Instead of promoting zero (or negative) population, encourage modest family sizes. Instead of driving a gas guzzling behemoth to work every day, take the bus or drive a modesty sized vehicle. Instead of keeping the thermostat at 75, turn it down to 65 and lower at night. The world could be a better place and it still can be but VHEMTwill not fly with the masses nor, probably, should it.
