Dark Side of Genetically Engineered Crops

The problem with any sort of natural engineering is that evolution will eventually find a way around it. This is an arms race that must be approached thoughtfully. How can we sufficiently control pests without applying so much pressure that it becomes advantageous to circumvent the controls?

Pest resistance to biotech crops surging: A new global assessment helps scientists explain why cases of pest resistance to genetically engineered crops increased by more than fivefold in the past decade, yet some pests remain suppressed Pest resistance to genetically engineered crops Bt crops is evolving faster now than before, researchers show in the most comprehensive study to date. But as expected from evolutionary theory, resistance can be delayed if farmers comply with recommendations to make use of abundant refuges. www.sciencedaily.com
