Genetically Modified Organism (GMO) - Myths and Truths Genetically Modified Organism (GMO) - Myths and Truths What are your thoughts on Genetically Modified Foods after watching this clip.
GENETICALLY MODIFIED MORE THAN 70 MILLION ACRES SINCE 1986. Does not require labeling. Process of breaking the natural boundaries that exist between species Produces desired traits Example: genes from salmon can be spliced into tomatoes to make them more resistant to cold weather HYBRIDIZATION The fertilization of the flower of one species by the pollen of another species
Hotly debated subject. In the 1930s, Milford Beeghly created new hybrids of corn that were more resistant to insects and easier to grow than the original strain. Many felt that this was against nature or immoral, but the hybrids proved to be commercially successful for the farmers that used them in their fields.
More than ½ of America's processed grocery products contain gene-altered ingredients. Splicing the genes makes the tomatoes crops larger when the weather is unfavorable.
