2) It is FAST approaching because human population is growing at an exponential rate. . . . But recently humans have gone to an exponential growth.
Actually, no, they haven't--and they haven't for a few decades.
"Exponential population growth cannot continue indefinitely for any species, whether it exists as microbes in a petri dish, wild salmon at sea, caribou in the taiga, or a global human society. However, world [human] population is no longer growing exponentially; it has been decelerating for the last half century or so, and UN projections show that it may actually decline after 2040."
http://en.wikipedia.org/wiki/Simon-Ehrlich_wagerThe above is an article about, among other things, Paul Ehrlich's dire (and mistaken) predictions of disaster:
"All of [Ehrlich's] grim predictions had been decisively overturned by events. Ehrlich was wrong about higher natural resource prices, about 'famines of unbelievable proportions' occurring by 1975, about 'hundreds of millions of people starving to death' in the 1970s and '80s, about the world 'entering a genuine age of scarcity.' In 1990, for his having promoted 'greater public understanding of environmental problems,' Ehrlich received a MacArthur Foundation Genius Award." [!]
The fact is that, over the last ten years or so, the world's human population has been its highest ever; and the percentage of the world's population that gets enough to eat has also been at its highest ever. Gosh. That means that people who were predicting starvation through overpopulation were wrong. Maybe those same people are wrong in their predictions of other disasters.
