3rd agriculture revolution. The Green Revolution was a period in time when new agricultural practices were created to help farmers all over the world. It was an international effort that was planned to eliminate hunger by improving crop performances. This plan provided new practices that allowed farmers to produce more of the same product within the same amount of land. This occurred during 1970s and the 1980s. The Green Revolution allowed scientists to create higher-yield hybrids that are adapted to environmental conditions in specific regions. This allowed scientists to predict the maximum annual crop yield in Asia and Latin America, which was about 6,000 kilograms per hectare
Genetacly modified orginisms is the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. The foreign genes may come from bacteria, viruses, insects, animals or even humans. Pros Resistance to insects tolerance to herbicides tolerance for heat, cold, or drought crop yield. Cons some people worry that GM foods may be linked to allergies, antibiotic resistance, or cancer.
Subsistence means they only grow enough food for them self. Sustainable agriculture is the production of food, fiber, or other plant or animal products using farming techniques that protect the environment, public health, human communities, and animal welfare. Intensive is when a lot of capital and labour is used to increase the yield that can be got. The use of pesticides for crops and medication for animal stocks is common. Extensive is an agricultural production system that uses small inputs of labor, fertilizers, and capital, relative to the land area being farmed.
