Genetically modified crops are plants that have been genetically altered to express desirable traits like herbicide or virus resistance, increased nutritional value, or environmental tolerance. While natural genetic evolution of crops like maize took 10,000 years, genetic modification can shorten this process to just a few years. However, some people have concerns about whether genetically modified food is safe, if it should be labeled, and what environmental effects it may have.

5. Plant Breeding and Crop Yield Tons per hectare

6. Peas (on the left) that make a genetically engineered bean protein are insect-resistant and do not need to be sprayed with pesticides.

8. What about their nutritional value and safety?
