Simple answer
Before... natural chemicals extracted from plants grown elsewhere.
After... pests with increased tolerance to the pesticide and a now useless "natural chemical," for both farmers who did and didn't use the GM product.
That is: when the pesticide is always present, as it is in BT potatoes, for example, BT resistant pests are artificially selected, leading to a pest population that is unaffected by what had been a useful tool for managing outbreaks.On Industry report touts potential for biotech crops to combat climate change posted 1 year, 4 months ago 13 Responses
