How can genetically modified crops affect the environment?

Genetically modified (GM) crops can impact the environment in various ways. They may lead to reduced pesticide use, resulting in less chemical runoff and improved biodiversity. However, concerns include the potential for GM crops to crossbreed with wild relatives, leading to unintended ecological consequences, as well as the development of resistant pests and weeds. Additionally, the reliance on specific GM traits can reduce agricultural biodiversity and disrupt local ecosystems.
