Genetic engineering is a scientific process that involves altering the DNA of organisms to achieve desired traits. This technology allows scientists to modify genes in plants, animals, and even humans, leading to advancements in agriculture, medicine, and research. For example, genetically modified crops can be engineered to resist pests or tolerate harsh environmental conditions, improving food security. The process often utilizes techniques like CRISPR, which enables precise editing of genetic material. While genetic engineering holds great promise for solving various challenges, it also raises ethical questions about the implications of altering life forms and the potential consequences for ecosystems and human health.
