Practical Applications
## What Are GMOs?
GMOs are plants or animals whose DNA has been altered by scientists to give them new traits.
## Why Modify Organisms?
- Improve crop yield and resistance to pests.
- Make foods more nutritious.
- Help crops survive in harsh conditions.
## Real-World Impact
GMOs are found in many foods around the world. They help reduce hunger and make farming more sustainable, but also raise questions about safety and the environment.
## Pros and Cons
- **Pros**: Higher yields, less pesticide use, improved nutrition.
- **Cons**: Concerns about allergens, environmental impact, and biodiversity.
Examples
- Golden rice is engineered to contain vitamin A, helping prevent blindness in children.
- Bt corn produces its own insecticide, reducing the need for chemical sprays.
