ANSWER: A GMO is a genetically altered organism whose genome has been engineered to introduce or
change a genetically controlled trait. Two main concerns include the safety of genetically
modified food for human consumption and the potential adverse effects of these organisms in
the environment (e.g., cross breeding of GMOs with native plant species). The benefits of
GMOs include: 1) pest-resistant crops (e.g., Bt crops) – less pesticide use; 2) disease-resistant
crops – the minimization of crop losses due to disease; 3) herbicide-resistant crops (RoundUp
Ready) – herbicides do not harm crop plants; and 4) altered nutritional content – increased
nutritional value (e.g., golden rice).
