I read a statistic that said without the major catasprophes - Plague, Spanish Flu, AIDS, Stalin, WW2 (and the generations the dead could have produced) the earth's population would now be over double what it is. Add in the 'smaller' wars, famines and epidemics, we'd probably be looking at a world population of 20 billion. Which, of course would produce famines, wars and epidemics of such a massive scale........
