Paying to find non-GE wild corn?

The chief of the University of Canterbury Plant and Microbial Sciences Department runs the New Zealand Gene Ecology organisation. (Jack Heinemann) (do google search in www.canterbury.ac.nz) Because bacteria can exchange genes to their advantage in the protected environment of a human cell it is necessary to take more care with drug resistance genes. We should not be feeding drug resistance genes to people en masse, not checking up with control groups if it is triggering anything. As bacteria make better bacteria we have to make better drugs. However in this case we are doing the opposite. We are giving the bacteria the genes to improve their resistance. The same is true with insects on the farm. 75 years ago simple natural pesticides work for my father. In the 50's and 60's the first generation of insecticides work very very well. We have had to keep making better insecticides and at the same time more specific ones. But as Jim admitted there is no drug that could cure his father's MRSA (methicillin resistant Staphylococcus aureus). It had to be left to nature to take its course with some nursing care (soap and water and bandages). We also learned how to extend their usefulness but he means `by' not `but'. refuges and IPM. When you plant bt corn or cotton you plant it in a checkerboard pattern with non-bt so some of the bugs will develop in non-bt and the development of resistance will be slowed a bit. Still there will be loss of effectiveness of organic bt to the organic farmers who only apply it when necessary, and have it active for a short period. With that use resistance does not develop. With the bt crops teh bt is there all the time and gradually weakens as the crop ages - perfect for development of resistance. If you want to blame some one for antibiotic resistant bacteria the water out of the sewer plant has several orders of magnitude more effect that crops possibly could because they are mixed with the pathogens at the sewer and in the environment and give them a chance to build resistance. Sewage is not being eaten by everyone. Also it will be worse with incompletely digested naked DNA from GM crops. |
