Genetic pollution, also known as gene flow, genetic contamination, or genetic assimilation, refers to the unintended spread of genetically modified organisms (GMOs) or foreign genetic material into the wild. It can have negative consequences on the environment and biodiversity, including the decline of natural species and the creation of invasive ones. Other terms used to describe genetic pollution include genetic erosion, genetic homogenization, genetic contamination, and genetic swamping. All of these terms suggest that genetic pollution poses a serious threat to the natural world, and it is important to address this issue through responsible development and management of biotechnology.
