Chapter 30: Conserving Earth’s Biodiversity: Case Study: back to extinction: o The ivory billed wood-pecker was though to be extinct because of human damage to their habitats and the already small numbers they had, but in 2005 they were rediscovered. 30.1: What is Biodiversity, and why should we care about it? o Conservation Biology—the goal is to preserve the diversity of living organisms both for its own sake and for the benefits that biological diversity provides for people. o Ecosystem services: Practical uses for Biodiversity: Biodiversity is simply the variety of life: the amazing diversity of living organisms, their genes, the ecosystems of which they are a part, and the interactions among them. Ecosystems directly and indirectly support us: Ecosystems are the processes through which natural ecosystems and their living communities sustain and fulfill human life. People use some ecosystem goods directly: o Hunting for food/ sport o Tamiflu is made from chemicals extracted from the seedpods of Chinese star anise Ecosystems benefit people indirectly: o Soil formation o Erosion and Flood Control o Climate regulation o Genetic resources o Recreation o Ecological Economics Recognizes the Monetary Value of Ecosystems services Ecological economics attemps to place values on ecosystem services and to assess the trade-offs that occur when natural ecosystems are damages to make way for human profit-making activites.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
