The Third Agricultural Revolution included biotechnology and genetic engineering. This Agricultural Revolution also involves the increase in chemical fertilizers. The Third Agricultural Revolution occurred during the later half of 20th century. During this time they started mass production of agricultural goods.
A GMO (genetically modified organism) 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. Food crops now include resistance to certain pests, diseases, or environmental conditions, reduction of spoilage, or resistance to chemical treatments (e.g. resistance to a herbicide), or improving the nutrient profile of the crop. Some pros of GMO foods are seeds are genetically changed for improving resistance to insects and generating healthier crops, according to Healthline.com. This can lower risk of crop failure, and make crops better resistant to extreme weather. Some of the cons are GMOs can pose significant Food allergies in children under 18 which have spiked from 3.4 percent in 1997-99 to 5.1 percent in 2009-11, according to the National Center for Health Statistics, though it should be noted that there's no conclusive scientific link to GMO foods allergy risks.
Subsistence farming is when a farmer grows enough food to feed their families. Usually this type of farmer grows different crops and has animals that will help feed and make clothes throughout the year.
Sustainable farming is when a farmer uses different resources to produce food, fiber or other plant or animal products. This way farming helps to protect the environment, people's health, communities and animals health. These farmers don't use chemical pesticides, synthetic fertilizers or genetically modified seeds. Their farming practices do not harm the water, soil or other natural resources. Examples are crop rotation, conservation tillage and pasture based livestock. These crops are safer for humans to eat.
Commercial farming is selling crops and livestock for profit. Producing crops and raising animals are done using the needs of the market.
