Before I leave for a few days, I thought I would point out that pesticides have many drawbacks, if one looks at the Gulf of Mexico, they have a dead zone from the accumulation of fertilizers and pesticides that have washed down into the gulf from ag land. Another drawback from large agri-business is that our arable land is a finite resource. Over cropping of the land cannot be made up for by fertilizing it with chemicals... it needs to rest, and if anyone remembers the Great Dust Bowl, we can lose this resource. Mono cropping is another bad idea, which leads to not only land exhaustion, but increases pests. My concern is GM, which does not stay in the land it is planted on, it moves to neighboring land, and infects organic crops. It also affects genetic biodiversity, as does monocropping. We really need to be thinking about these things as a a nation and as a species, because I think we tend to believe that our farmland and ability to produce food is a "given". That could change overnight. Climate change could devastate our agriculture, and unless we have some diversity in our crops, it could impact us even deeper. Now I am off to the train... have a nice week everyone.
