Genetic Engineering Agriculture

Genetically modified organisms (GMOs) — plants, animals, or microorganisms whose genetic material has been altered using genetic engineering techniques — have been the most bitterly contested technology in agriculture since their commercial introduction in 1994. GMO crops are now grown on 202 million hectares globally (12% of all cropland) in 29 countries, primarily corn, soybeans, cotton, and canola. The US grows 40% of all GMO crops globally; the EU restricts them severely. Scientific consensus (from over 2,000 studies): GMO foods currently approved are as safe to eat as their non-GMO counterparts — the National Academies of Sciences, WHO, and 280+ scientific and medical organizations agree. Specific applications: Bt crops (produce their own insecticide from Bacillus thuringiensis bacteria — reducing pesticide use 37-45%); herbicide-tolerant crops (Roundup-Ready — allowing no-till farming but creating herbicide-resistant 'superweeds'); Golden Rice (fortified with beta-carotene/Vitamin A to address deficiency affecting 250M children — delayed by regulatory controversy and activism for 20 years). Disease-resistant crops (papaya ringspot virus resistance saved Hawaii's papaya industry). New generation: drought-tolerant varieties for climate adaptation; myostatin-knockout cattle for meat efficiency.
