Although third world countries do have a far larger population than industrialized nations, and the trend is constantly increasing, their populations should not bear the responsibility for our population-induced degrading environment. The cheap write my essay security domains and strategies we make on the biosphere is sometimes expressed mathematically by ecological economists as I = PAT. I being impact, P population, A affluence (consumption)and T technology (environmentally bad technology) (Ehrlich and Ehrlich, 1990, p.24).
