From what I've seen, so far the emphasis seems to be on immigratio
Overpopula
While it is true that global population
You are correct that world population
Nicodemas is right! I just moved back to the states after living in Mexico for five years. Having lived not in a gated community or tourist area, but a casa on the streets of Tepic, I can attest to the fact it is the cultures and governments that make the difference. It has nothing to do with "race" or geographical placement.
America has led the world on population growth control since the "baby Boom" of the forties and fifties ( I was born in 45) and remember the discussions and solutions of that problem well, Birth control, Family planning, Roe Vs. Wade (abortion). While we ran head long into these solutions I remmember how the "third world" scoffed at it as an American conspericy to thin out the non-white of the world and wouldn't perticipate. Now because of mass immigration from Mexico to the USA thay have started a program in Mexico to supply free Viagra to the people. Go figure! Why don't the just keep their people there and incourage the illegals back?
