People can fall into the trap of blaming the poor of developing countries for the problems of the world since it is poor countries that have these massive, ballooning populations. Is is true that overpopulation in poor countries exacerbates the living conditions in those countries, but bear in mind that the average middle-class citizen of a Western nation consumes more than a hundred times the volume of resources of the average poor citizen of a developing nation. Armory Lovins calculated that the average American consumes 250 times the resources of the average Nigerian. This means that the United States has the global impact of seventy-five trillion Nigerians. I’ll go one step further: I’ll bet American citizens consume more Nigerian resources than Nigerians themselves.
