You are aware that mankind has subjected itself to avoidable suffering for as long as we could swing a stick, right? We have hundreds of millions suffering (avoidably might I add) right now and even if we somehow managed to keep Earth squeaky clean - I see a lot more avoidable suffering for the millennia to come.
If anything, significantly reducing Earth's capacity to sustain humans may paradoxically result in diminished total human suffering (average suffering x number of humans) due to lower population.
For what it's worth I do care, courtesy to my overly empathetic neural wiring. I'd argue that I am doing a lot more than my peers to reduce future human suffering simply by not contributing to the overpopulation. Not that any of it matters in the grand scheme of things ;)
Can't speak for dublinclontarf, but personally I'm not too concerned for the environment simply because I'm fairly indifferent as to whether mankind makes it or not.
The Universe has been doing quite well without us for billions of years and will continue to do so if we are too dumb to keep our little rock habitable (which I suspect may be the case).

Keep fighting the good fight, I admire your zeal!
