First Agricultural Revolution

The first agricultural revolution was the transition of humans from nomadic hunting and gathering to agricultural production of domestic plants and animals. It started around 11,000BC. During this time humans dramatically changed their behaviors and became more civilized. It changed the way humans live by making many technological advances possible and allowed the population to grow dramatically.

The third agricultural revolution, also called the green revolution, was a time that was an international effort to reduce hunger by improving crops. The third agricultural revolution occurred through the 1970s and 80s. There was new advancements in crops including GMO's and GE's.

GMO's are being put in the crops to make farming more efficient.

Genetically Modified Organisms

Genetically modified organisms (GMO's) are when a gene from an organism is changed or removed to improve the crop. The main purpose of GMO's is to reduce or eliminate the use of pesticides. The pros of GMO's are resistance to insects, and tolerance to heat, cold, or drought. Cons are that they can be potentially harmful to your health.
