Theres alot of talk about overpopulation. Copying the Chinese sysetem of the 1 child policy, should something similar to this be introduced worldwide? I resently covered a unit in Geogrpahy centering on population and population control. It is obvious something needs to be done and this type of control is proven to work. Even possiably a 2 child limit would be fine. When the parents die the children replace them in terms of population numbers. While it sounds cold and harsh this type of plan is an effective one. In terms of energy for the future renewable sources are the most practical option. Wind, solar, tidal, water and theromonuclear are all option which are enviro friendly and supply ample amount of energy. In 1999 (i think it was a 1999 report, can't find it at the moment) wind power was considered to be as cheap and as effective to set up and maintain as any other conventional power source. A combination of these renewable power sources will easily solve any power issues we have in the future This is all ashuming we don't blow each other up of corse
