1.4 acres per person today? WOW, thats phenominal.According to the latest figures I could find (2002), there were approximately 6,200,000,000 people in the world. The surface of the earth contains about 36,660,000,000 acres of land. If we assume 10% of that is arable (the figure is actually much higher than that), then that leaves us with 3,660,000,000, or roughly 1.4 acres of arable land per person. Keeping in mind that we don't need to live on arable land, and we can get food from the remaining 70% of the earth that is covered with water, we are hardly short of space.
May I ask where the "stable population" birth rate came from?According to UN data, the average European woman of child-bearing age is likely to have 1.4 children, down sharply from 2.0 in the early 1970s. The minimum needed for a stable population is 2.1.
If...The current U.S. growth rate of 1% is being maintained largely by immigration.
I was racking my brain to come up with a better source than Hawking but Einstein was pre-occupied with the atom bomb apparently.The growth in population has already created exceptionally complicated economic, social, and psychological problems, and will in the future inevitably pose still more serious problems. In a great many countries, particularly in Asia, Africa, and Latin America, the lack of food will be an overriding factor in the lives of many hundreds of millions of people, who from the moment of birth are condemned to a wretched existence on the starvation level. In view of this, future prospects are menacing, and in the opinion of many specialists tragic, despite the undoubted success of the "green revolution".
