Third Agricultural Revolution- Technological innovations and scientific farming methods have been added into our food gathering process. Mechanization, chemical applications, biotechnology, and more were also added to help improve our food. Gas and diesel engine tractors are used in fields for our plants to help obtain them and make the process faster. There is a much reduced number of workers, and an increased land mass of area to grow crops, and monoculture.
Genetically Modified Organisms- Plants and Animals changed as a result of biotechnology. By adding them in our life they could grow faster and make us healthier, or just the opposite.
