In considering this topic, we need to KNOW that out of more than 220 Global countries in more than 110 the fertility rate is already less than 2.1 child per woman . For that reason we need to find the ways to encourage countries like Nigeria, Rwanda, Madagascar, India and many other poorer countries to educate their people to reduce fertility of more than four or five ch/woman to the replacement level of 2.1 ch/woman. Only than we could hope that standard of living in most countries would reach a comfortable sustinance level, and save the local environmental health. Dan Kustudich
