Shaking polin off from one plant to another is selective breeding: put gene(trait) from one corn to another (intrabreeding) Interbreeding is between different species (more of a mutation) U. s. argentina, brazil, canada, india china and 16 other countries. Gm foods most include - soybean, some - cotton, canola, corn: herbicide resistance and insect resistant. Precautionary principle doesn"t lead to huge profits. Pesticide is combination of fungicide, insecticide etc. Bioaccumulative accumulate as you go up the food chain, will affect people or peoples ability to reproduce. Evolutionary arms race with pests in the reason for all the pesticide. \ Some pests can be genetically different and immune to some sort of pesticides, they will than breed with each other and offspring will be immune.
