I read a study that said that population would stop at 6 billlion automatically. However, that is 3 times greater than today. Water would be important and a water shortage would be as great or greater disaster than an oil shortage. Amazing that efforts to spread birth control in the 3d world were stopped by religious fanatics in the USA; however, poor people like to have a lot of children, so who knows if birth control would have worked. China has a one-child policy. I don't think it is good to have religious fanatics running the USA, when they control UNESCO policies, etc. Liberals should have been in control; I don't think that would have saved the world, but it might have been better for the general welfare of people (birth control). What about Israel and surrounding countries. An article in YaLibnan said Lebanon is one of the most unsustainable countries, too many people on too little land. May be true of Israel also, too many people on too little land. Nuclear energy may grow; however, like the BP oil spill in the Gulf, I still have nightmares that another accident like Chernobyl can happen. Americans are afraid of nuclear energy. However, if you take 6 billion as the peak and a steady decline afterwards, which might be due to the inability of earth to hold more people as the reason for a decline after the peak, from wars, starvation, lack of resources, etc. you might be more realistic.
