Evere since the existence of planet,some millions of years ago till 1950,the world population was 2.43 billion.year 2007 it is 7 billion.2050 it will reach atleast 11 billion.There will be more deseases,poverty and crime than ever before.once rome ruled the world,brits once us now china will. I think nuke will come handy one day for the distruction of mass and for the well being of the left over population
