Genetic Modified Organisms

GMO´s ( genetically modified organisms), are plant or animal created by techniques of biotechnology.
This experimental technology used DNA from differents species, creating a combinations of plant, animal, bacterial and viral genes cannot occur in nature.

A plant with a desired trait is chosen and reproduced to produce more plants with the desirable trait, and plants with this technology are called transgenics. 

When this process is used to produce insect or herbicide resistant plants, they are referred to Genetically Modified Crops.
Countries that grow GM crops include; Argentina, Australia, Canada, China, Germany, India, Indonesia, Mexico, Portugal, South Africa, Spain, United States, Ukraine, and many more.
GMO´s have different uses like: 

• Pest resistance
• Herbicide tolerance
• Disease resistance
• Cold tolerance
• Salinity tolerance
• Nutricion
• Pharmaceuticals
• Phytoremediation

I think that Herbicide tolerance, cold tolerance and disease resistant are the most important once, the GMO are used like food for many people and for that reason the food industries incorporated this technology. The diseases resistant and pest resistance have a positive results because that permit the less used of chemicals, and that contribute to people health, and the cold tolerance permit sow in cold places that usually you can`t sow. This is a topic you have keep in mind.
