Jamaal, dont get me wrong i am not trying to say that you dont have a point, but i have heard this argument numerous times, i agree with you that herding/nomadism is not good for the environment, it does lead to desertification, but neither is intensive farming (ddt -which is consequently banned in europe and america but was happily dished out to the third world untill recently-, geneticly enhanced crops -do you want Monsanto controlling what farmers grow?- fertilisers and pesticides -which polute the land, water system and the animals that live on the land- and so on). On top of that intensive farming is the only option if you want to feed a pupulation of millions and growing . however the link between economic prosperity and farming i dont see, most of the worlds population of farmers live in dire poverty (put a search into google for poverty and farmers and see how many horrors you get),its only european and american farmers that do well because they are subsidised by their countries eu and american farm subsidies is a hot economic topic because its against the rules of fair competition in an open market, thus leads the earlier problem of starving farmers (a paradox i know) even worse if we are thinking about in on an environmental level, the world does already produce enough food to feed its population, however its against economic advantages to feed everyone at the expense of all - not high enough profit margins. again the point on the war and fighting over land, why would a fertile crescent be any less attaractive to those seeking power than a patch desert, people fight over the smallest bit of land that contains nothing because they are terretorial animals, which doesnt excuse them, and further i refuse to belief that we're all refugees because people are fighting over land, their fighting for power, land comes with power.
