This unit explores human activities that disrupt ecosystems both positively and negatively and the methods employed to reduce impact. It examines human use of natural resources through many means, including mining and clearcutting, and the impacts on the environment. In Part 2 of Unit 5 we will describe and explain concepts related to the tragedy of the commons, clearcutting, mining and urban land use.
