For the guy who asked about farming:
Agriculture, also called farming or husbandry, is the cultivation of animals, plants, fungi, and other life forms for food, fiber, biofuel and other products used to sustain human life.[1] Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. Agriculture generally speaking refers to human activities, although it is also observed in certain species of ant and termite.[2][3] The word agriculture is the English adaptation of Latin agricultūra, from ager, "a field",[4] and cultūra, "cultivation" in the strict sense of "tillage of the soil".[5] Thus, a literal reading of the word yields "tillage of fields".
