Biodiversity loss is a significant concern in genetic modification because it can lead to reduced genetic variation within crops and among other species. When certain traits are favored through genetic modification, there can be an over-reliance on a limited number of genetically modified varieties. This reduction in the pool of genetic diversity can make crops more susceptible to diseases, pests, and changing environmental conditions; without a variety of genetic traits, the entire system may be less resilient. Moreover, a lack of genetic variation can hinder the ability of ecosystems to adapt to new challenges, potentially leading to ecological imbalances and a decline in overall species health. Thus, maintaining biodiversity is crucial to ensure that ecosystems remain robust and capable of adapting to future changes.
