The world is not overpopulated nor will it be.
We are seeing the fertility rate in the entire developed world, including China and India dropping. The developed world is way below replacement rate meaning that they populations are either in decline or about it.
China will be half the population by 2070 or 2080. Japan is losing 450K of their native population each year. Russia and Germany are seeing their working populations shrinking (people get old before they die).
Thus, you wrote an entire article based upon no facts.
The fertility rate in my country is not dropping and now the country is no longer save because of this reason, parents gave birth to children they can't cater for and they end up becoming problem in the society... I think a nigerian will understand me better and some other country and probably i should not have generalized it using world?
