That is neither judgemental nor biased, whilst being honest, clear and to the point … and in those few words, your faith in humanity is given a little boost.
Global Warming and Sustainability are, indeed separate issues. They share, however, a common warning: life as we know it must change. Not, “we must change because we’re evil” but rather, one way or another, things are going to get different. Even without warming, a population doubling every 50 years will inevitably outgrow the Earth, if not tomorrow, then certainly in a few hundred years. Add in warming and I think “tomorrow” is not hyberbole. But fine, do nothing. Things will still change.
