Sticking to food production for the moment, one of the refrains I hear constantly from people skeptical of claims of increasing food production is that current farming techniques are unsustainable because they rely on manmade pesticides and fertilizers. I happen to think that claim is spurious, but it is also largely irrelevant.
Almost every week a new major discovery is reported in efforts to create more effective farming technologies which often turn out to be far more “environmentally friendly” than current methods. In July, for example, it was announced that Colorado State entomologist Louis Bjostad has made significant progress in developing a natural way to rid corn of the Western corn rootworm, responsible for up to $1 billion in annual crop losses.
Bjostad discovered the rootworm eats corn because of carbon dioxide given off by corn roots. He and his researchers are working on pellets and granules of yeast, baking soda and other materials which could be placed in corn fields which would confuse the rootworms by giving off carbon dioxide. If it works, Bjostads discovery would not only be safer but far cheaper than using conventional pesticides.
Bjostad plans to do two more years of field tests to identify which compounds and mixtures are most effective in dealing with the rootworm.
