What are the ethical concerns associated with genetic modification?

The ethical concerns associated with genetic modification often center around the potential impacts on biodiversity and health. Genetic modification can lead to a decreased diversity of crops as genetically modified organisms (GMOs) may outcompete traditional varieties, leading to a reliance on a limited number of genetically modified strains. This homogeneity can make ecosystems more vulnerable to pests and diseases, thereby threatening food security in the long term.

Health impacts are also a significant concern. There are ongoing debates regarding the long-term effects of GMOs on human health, as the introduction of new genes can result in unintended consequences. These impacts may include potential allergenic reactions or unknown health effects not yet fully understood by scientists.

While the other options mention benefits of genetic modification, they do not address the ethical implications that arise from the technology. Increased agricultural productivity, enhanced nutrient content in crops, and utilization of renewable resources focus on the advantages and improvements brought about by genetic modification rather than the ethical dilemmas and risks that need careful consideration.
