James Brown (ecologist, and a Distinguished Professor of Biology at the University of New Mexico) quoted by Professor Paul Ehrlich (2013): “Can humanity avoid a starvation-driven collapse? Yes, we can – though we currently put the odds at just 10 percent. As dismal as that sounds, we believe that, for the benefit of future generations, it is worth struggling to make it 11 percent. One of our most distinguished colleagues, biogeographer and energy expert James Brown of the University of New Mexico, disagrees. He puts the odds of sustaining human civilization at 1 percent, but thinks that it’s worth trying to increase it to 1.1 percent” (Paul R.
