Feeding the World

4 types of Farming Subsistence: Farming that involves only rearing enough animals and/or growing enough crops to support immediate friends and family. Cash Crop: A cash crop is an agricultural crop which is grown for sale to return a profit. Intensive: Intensive farming or intensive agriculture is a kind of agriculture where a lot of capital and labour are used to increase the yield that can be obtained per area. Extensive: Extensive farming or extensive agriculture (as opposed to intensive farming) is an agricultural production system that uses small inputs of labor, fertilizers, and capital, relative to the land area being farmed.
