Protecting Biodiversity Subscribe

In Module 2 you learned about Earth’s history of mass extinctions and the threat of global climate change. You also explored ways that economic growth can both help and harm Earth’s biodiversity. In this module we learn more about economic principles: how they apply in the natural world, and how they drive some of the positive and negative effects of economic growth on biodiversity. For this discussion, read the article: "Special report—Biodiversity: Hearts and minds." The Economist 408.8853 (Sep 14, 2013): 10.

What is the driving force of the destruction of the elephant population? What other trades are mentioned as threats to specific animal populations? Choose one to research further and describe the market demand for the product related to the animal at risk. Are any regulations in place? How are these regulations enforced?
