The potential negative impacts of genetically modifying plants to release a protein that kills insects may include:
1. Environmental concerns: Some people may be opposed to the idea of genetically modifying plants as it may have unintended consequences on the environment. For example, the modified plants could potentially harm non-target insects or disrupt the ecosystem in unforeseen ways.
2. Ethical concerns: Some people may have ethical concerns about genetically modifying plants in order to kill insects. They may believe that it is unethical to manipulate the genetic makeup of plants in this way.
3. Health concerns: There may be concerns about the potential effects of consuming genetically modified crops that have been engineered to produce insecticidal proteins. Some people may worry about the long-term health implications of consuming these modified plants.
4. Economic concerns: Farmers who rely on pesticides to control insect damage may be opposed to this research program, as it could potentially reduce the demand for pesticides and impact their livelihoods.
Overall, opposition to this research program may stem from concerns about the potential environmental, ethical, health, and economic impacts of genetically modifying plants to release insecticidal proteins.
