Can the earth honestly sustain human food consumption needs?
. Mugatu50 – Perhaps the best answer I can give you is to say that people have had the same worry as you for well over two thousand years now. It is human nature to worry about resources – paradoxically it is one of the reasons why we are so resourceful! Instead of running out of food, we have more now, per person, then we have ever had before. If you want to read an analysis that answers your worries by a scientist working for the US Government, I can thoroughly recommend Indur Goklany’s paper on sustainability and biodiversity,available here: http://www.cato.org/pubs/pas/pa-175.html Weise Ente (above) is of course correct to point out that more than water and sun is needed to sustain plant growth – Co2 is also a vital factor, and this is increasing (:-P). Phosphorus and other elements are not irreplaceable, though, as hydroponics (the growing of food in chemically enhanced water) proves. Human ingenuity is boundles
