8.22—Risks and benefits of GM organisms

Genetic modification can add a useful characteristic, such as producing a medicine or resisting a pest. Its value depends on effectiveness, containment, ecological effects, ownership, welfare and who receives the benefit.

Benefits may include reliable therapeutic protein production or reduced losses; risks include unintended gene flow, resistance, ecological disruption and ethical objections to animal or food applications.

A GM microorganism making insulin is contained and purified, whereas a GM crop releasing a trait into wild relatives raises a different monitoring problem.

“GM” is not automatically safe or harmful. Judge the specific organism, gene, environment and evidence rather than using a blanket claim.
