Still following the post above check a recent paper below published in the journal Futures by a researcher of the Centre for the Study of Existential Risk at the University of Cambridge:
"...Of course, one hopes our civilization never collapses and subsequently goes extinct. But if Death does come knocking at our door, then it seems that we will have acted far better if we have not cut the human-biosphere umbilical cord until absolutely compelled to do so by forces beyond our control. It may not be merely the extinction of humanity, as Henry Sidgwick first proposed, but loss of the entire biosphere and the atmosphere it supports that truly constitutes “the greatest of all conceivable crimes"
It´s rather interesting to see how Cambridge and Oxford universities (which also have an Institute that is worried about the extinction of Humanity) are so pessimistic about our future. See for instance a book (cover below) by a Senior Researcher fellow at the aforementioned Oxford-affiliated Institute, Toby Ord http://www.tobyord.com/
