Unit 6: The Bare Necessities: Land and Food Text: Test: Chapters 10+11 Friday 2/8 Description: All human activities require land, and our societies have spread to every corner of the globe. In this unit, we will investigate the major demands humans place on the limited amount of land on Earth and what environmental impacts these demands cause. We will pay special attention to agriculture, and how various practices can harm or benefit the environment. As always, our focus will remain on evaluating the impact of human activities on environmental systems and finding sustainable practices. Essential Questions: 1) What are humanityâs demands on Earthâs land resources, and what limits exist on those resources? 2) What organizations and policies can promote sustainable land use, and how? 3) What practices characterize modern industrial agriculture, and what are its benefits and drawbacks? 4) How can we reduce the impact of agriculture on the environment and promote sustainability?
