Genetic engineering concerns the application of scientific alteration of plant and animal DNA in order to combat pests, disease, drought, and other factors which can adversely harm the organism. Objections to genetically modified organisms (GMOs) include theological (playing God) and economic (GMOs can be costly) viewpoints. Genetic engineering of both plants and animals must pass through FDA legislation, which may include public labeling of the product or otherwise marking it as genetically modified.
