2.5 Cultivation
Most of human kind depends for food on cultivation—people's intervention in nature to promote the growth of domestic plants —and animal husbandry. Cultivation is a complex relation among human beings, their crops and livestock, and the soil, climate, wild vegetation, and so on. The location of the cultivation sites is therefore strongly under the direct influence of natural conditions, especially of soil and climate; of social and cultural conditions among people, and of their technical activities; of the biological character of the crop or herd; and more particularly, of a complex interplay of all these elements.
