luckily they dont use much, mainly because its too expensive.
there is also the angle of the efficiency of farming. modern agriculture uses more energy in the form of petrol than it produces. its crazy to grow veg in huge quantities on the other side of the world, with massive chemical input, and then transport it to shops, where people drive in their cars. as we here all know growing veg is relatively easy and fun. as Peak Oil starts to hit, more and more of us are going to have to do it. if we dont regard chemical fixes as REALLY the last resort for some VERY difficult areas, our environment will quickly become an even worse chemical soup than it is now. (i can taste the pollution when i come to uk cities, and uk tap water is undrinkable!)
and as i said, who here wants to financially support the likes of monsanto? (agent orange, bovine growth hormones, GM maize, to name a few of their crimes).
