- less land destroyed
- natural land preserved
Weedy species
- Decreased use of pesticides
- increased diversity of insects
- cleaner water
Monarch caterpillar on leaf dusted with bt pollen
Concerns
- Pollen from insect - resistant crops harmful to wildlife
- 1999 experiment on bt pollen and Monarch caterpillars
recent experiment suggests to be false
- Crop diversity will decrease
- studies show genetically, crops have not been affected by GM crops
- Invasive species
- risk of GM crops
- needs to be controlled
Crop diversity
