Biological diversity, or biodiversity, has become a topic of great concern among conservationists. Biodiversity is often used by scientists and policy makers to help determine the health of ecosystems. (a) Describe TWO characteristics shared by ecosystems that have high biodiversity. (b) Identify TWO specific human activities that result in a loss of biodiversity, and explain how each activity lowers biodiversity. (c) For each human activity you discussed in (b), propose a practical strategy (other than simply banning the activity) to reduce the loss of biodiversity. (d) Describe ONE naturally occurring factor that could lead to a loss of biodiversity. (e) Describe TWO ecological benefits that greater biodiversity provides.
