Insects are a major danger to crop plants. Every year, insect damage destroys many plants that could be used to produce food. Genetic engineering can be used to insert a gene into crop plants that helps them resist insects. In addition to allowing future populations of the plant to obtain pesticide resistance, what is one potential risk of this use of biotechnology as it relates to other crops they may be growing in the field as well?
