"The worst thing that can happen, will happen, is not energy depletion, economic collapse, limited nuclear war or conquest by a totalitarian government. As terrible as these catastrophies would be for us, they can be repaired within a few generations. The one process ongoing in the 1980s that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us." (E.O. Wilson, 1980).
