Name two benefits and two concerns of genetically modified food.

Benefits:

1. Increased crop yield: Genetically modified plants have been engineered to be more resistant to pests, diseases, and harsh environmental conditions, leading to higher yields.
2. Enhanced nutritional value: GMOs can be designed to have higher levels of essential nutrients, making them more nutritious for consumers.

Concerns:
1. Environmental impacts: There are concerns that GMOs may have negative impacts on biodiversity, such as the potential for cross-contamination with non-GMO crops and the development of superweeds.
2. Health concerns: Some people worry about the potential long-term health effects of consuming GMOs, as well as the use of antibiotics and hormones in genetically modified animals.
