  1. Humans are ethically responsible for protecting endangered species.

  3. The current rate of extinction is high and human activities threaten biodiversity at all levels.
  4. Humans  have  greater  medical  needs  than  at  any  other  time  in  history,  and  many  potential  medicinal compounds are being lost as plant species become extinct.
