That tells me is that 1) life itself is pretty special and 2) that humans are extra special.
Yes, we're rapidly making the planet less habitable for us and other large species. Nonetheless, we have special mental capacities that are almost certainly unique to us ... how well we use those special attributes is another matter.
Given human nature, it's been inevitable that at some stage we'd become so dominant that we'd deplete and pollute the environment and eventually have a big cull off. The population obviously can't keep increasing forever with natural resources rapidly dwindling. Talk about destiny ...
Still, the inevitable culling of billions does not mean humans will die out entirely or even necessarily lose our technological advances. A smaller human population may yet make incredible strides in the future, including habitation of Mars or even beyond.
'Scientific views end in awe and mystery, lost at the edge in uncertainty, but they appear to be so deep and so impressive that the theory that it is all arranged as a stage for God to watch man's struggle for good and evil seems inadequate.'
'We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.'
Richard Feynman agrees. : )
