Q.Deliberate release of GMOs (Genetically Modified Organisms) into the environment could have negative ecological effects. Write the possible risks of GMOs.

GMOs carry ecological, health and socio-economic risks -- including harm to non-target species, gene flow to wild relatives, resistance evolution, food-safety concerns, and reduced biodiversity.

While genetically modified organisms (GMOs) offer benefits such as pest resistance and improved yield, several risks are associated with their use. Ecologically, an introduced toxin (e.g., the Bt toxin in Bt cotton) may unintentionally harm non-target, beneficial organisms such as pollinators or natural predators of pests. The transgene can also 'escape' via cross-pollination into wild or weedy relatives of the crop (gene flow), potentially creating herbicide-resistant 'superweeds' or altering wild gene pools. Continuous exposure of pests to a single toxin can drive the evolution of resistant pest populations over time, reducing the long-term effectiveness of the GM trait. On the health side, there are concerns that a newly introduced protein in GM food could act as a novel allergen or have unforeseen toxic effects in consumers, requiring careful biosafety testing before approval. Large-scale adoption of a single high-yield GM variety can also reduce the genetic diversity of a crop species (since most farmers grow the one variety), making the crop …

Releasing GMOs into the environment carries risks of unwanted gene spread, ecological disruption, and loss of biodiversity.

One major concern is gene flow: pollen from a genetically modified crop (for instance, one engineered for herbicide resistance) can cross-pollinate related wild or weedy plant species, potentially transferring the introduced trait and creating hard-to-control 'superweeds.' GM crops engineered to produce insecticidal proteins may also unintentionally harm non-target organisms, including beneficial insects like pollinators, if those species are inadvertently exposed to the toxin. There is also the broader ecological risk that a genetically modified organism, if it escapes cultivation, could outcompete native species and disrupt the balance of natural ecosystems, reducing local biodiversity. Finally, continued exposure of pest or weed populations to a si …
