*begin quote* I have been under the impression that the world's current population cannot be fed without the use of chemical fertilizers. <...> Nevertheless Dr Ivette Perfecto of U Michigan is quoted in the press as stating otherwise, based on a modeling study. http://www.planetark.com/avantgo/dailynewsstory.cfm?newsid=43040 *end quote* Perfecto! Especially if the growing season is extended at high latitudes! ;-) -dl (PS, must be mindful of the delicate balance between organic fertilizer emissions and associated methane release on the one hand, and the release of methane sequestered in permafrost should high-latitude growing seasons be extended a bit too far, on the other. In case you haven't noticed, this is a long winded fart joke.) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
