Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate?

    Absolutely! Once something is extinct, it's gone forever. Humans have a duty to the earth to preserve as much as possible. It's also been argued that we do not know how valuable these plants and animals might be to people and the planet in the future.

What are the pros and cons that you see in this latest trend? Give examples of the potential environmental impact.
