Opinion (Paul Ehrlich, Bing professor of population studies at Stanford University in California): “The optimum population of Earth – enough to guarantee the minimal physical ingredients of a decent life to everyone – was 1.5 to 2 billion people rather than the 7 billion who are alive today or the 9 billion expected in 2050, said Ehrlich in an interview with the Guardian.
“‘How many you support depends on lifestyles. We came up with 1.5 to 2 billion because you can have big active cities and wilderness. If you want a battery chicken world where everyone has minimum space and food and everyone is kept just about alive you might be able to support in the long term about 4 or 5 billion people. But you already have 7 billion. So we have to humanely and as rapidly as possible move to population shrinkage.’…
“But he agreed with the Royal Society report that said human population and consumption should not be divided. Source: Raw Story (http://s.tt/1daUI) ‘[They] multiply together. You have to be deal with them together. We have too much consumption among the rich and too little among the poor. That implies that terrible thing that we are going to have to do which is to somehow redistribute access to resources away the rich to the poor. But in the US we have been doing the opposite. The Republican party is wildly in favour of more redistribution, of taking money from the poor and giving it to the rich.’”
My Comment: The only help is to educate everyone in the spirit of unity and mutual guarantee, which will solve all the problems because people will develop a sense of social responsibility for the sake of revealing the Creator.
