Which of the following are documented effects of using GMO crops? Check all of the correct answers.

- Reduced use of pesticides
- Less land cleared for cropland because of increased crop yields on existing land
- Increased resistance to herbicides in some weed species
- Increased profits for farmers
- Increased cancer risk in people who consume GMO foods
- Gene mixing between wild species and GMO species

GMO crops have documented benefits such as reduced pesticide use and increased profits for farmers, contrary to the unsupported claim of increased cancer risk in consumers.

Explanation:

Reduced use of pesticides is a documented effect of using GMO crops as they are engineered to be resistant to specific pests, reducing the need for chemical pesticides. Increased profits for farmers is another benefit, with studies showing higher yields and cost-effective farming practices with GMO crops. However, increased cancer risk in people who consume GMO foods is not supported by scientific research and no conclusive evidence exists regarding this claim.
