National Action Network, the group I founded, has affiliates or chapters in over 40 cities around the country.

Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat. If the right policies toward nature were pursued, we would need no zoos at all.

Zoologists study the behavior, physiology, classification and distribution of animals, whether they are living or extinct.

Zoologists may find jobs working for government agencies, non-profit organizations, universities, museums and zoos.
