What can be done to protect biodiversity?
Why You Should Care
By now, you have learned several reasons that biodiversity is important to our lives and the biosphere as a whole. There are many ways that you yourself can protect biodiversity. Simply living as "green" as possible protects natural resources and decreases the pressure put on natural areas. Supporting smart urban planning is another way to protect biodiversity: Re-developing land that has already been in human use and strategically locating new development both serve to protect natural areas. There are many non-governmental agencies that also work to either preserve natural areas or endangered species. "Charismatic" species like tigers and pandas are often the focus of conservation efforts, but protecting them also means protecting entire ecosystems.

Short-Answer Questions
Suppose that, in the course of surveying streams that would feed into a hydroelectric dam that is already in the process of being built, researchers find a small species of minnow that has not previously been described to science. It apparently only lives in a few streams and needs small, shallow, fast-moving water to survive, so when the river backs up, covering the streams after the dam is closed, the minnow would most likely be extirpated and possibly become extinct. According to the U.S. Endangered Species Act, this minnow should be protected, which would mean stopping construction of the dam that has already cost millions of dollars in taxpayer funds and that would provide much-needed cheap electricity and flood control to an impoverished area.

You could hypothesize that the minnow might be important food for sport fish, but that’s really a guess.
2) It’s difficult to decide whether or not a species should be protected from extinction when allowing its extinction would provide many benefits to people. Obviously, many people would have many different stakes in this decision, so you could predict, say, that the politician would support his constituents’ needs, his constituents would probably want the electricity, the scientist would support the minnow’s intrinsic right to exist, etc.
