Describe and give examples of Habitat on Adaptation and speciation.
explain how species diversity promotes adaptation and survival in changing environments.
Bob Davison describes the Endangered Species Act (ESA) as an effective tool for conserving biological diversity. What is his rationale for the value of focusing on individual species?
The public is not concerned about the economic costs of individual species recovery.
A focus on individual species is cheaper than protecting entire ecosystems.
Establishing public empathy for charismatic species provides an opportunity to educate people about lesser-known species.
The public tends to value intact ecosystems over particular plant and animal species.
