Summary
Definition
GMOs are living organisms whose genectic property was modified by humans to give them new properties.
GMO Examples
Golden rice
Long preservation tomatoes Corn insecticide
Resistant rapeseed pesticide
Risks
1. Toxic risk associated with the ingestion of pesticides by the consumer
Risks
2. Microbiological risk with a possible worsening of the antibiotic resistance
3. Toxin production and allergenic effects of GMOs for the body
Health benefits
The introduction of a modified drug in the bone marrow cell gene has enabled children with immune deficiency to restore a completely normal and functional immune system. They are cured and live a normal life.
GMOs also allow plant to better withstand the rigors of the weather and thus survive in areas too dry for them
Health benefits
The wealth of some molecules allows their use preventively ("golden rice" very rich in vitamin A can reduce the risk of blindness in developing countries) or for therapeutic purposes
Health benefits
Lack of perspective
GMOs are too recent to measure all its risks. Some opponent groups are demanding its ban on the "principle of security”. We mustn’t use Humans as Guinea pigs.
Disadvantages
the risk of contamination by transgenic pollen between varieties
polluting the environment
GMOs in France
The cultivation of GMOs in France is authorized in principle by the E U but should not be used because of national prohibition.

Conclusion
The GMOs are an advantage for the economy because they are less expensive than the traditional growings, and easier to maintain, but this solution does not suit everybody, because of the risks for the health and for the environment, and because of the lack of knowledge about it.
