A conservationist is someone who is dedicated to preserving and conserving something which usually is irreplaceable or very hard to replace. Generally though, a conservationist is considered someone who wants to conserve and preserve the environment, natural resources, ecological systems and their components. For now, conservationists shouldn't be confused with restorationists because the philosophies behind these two camps are considered to be pretty different and sometimes can conflict. In a nutshell, conservationists want to keep what's disappearing from continuing to disappear. Restorationists, however, want to re-introduce and bring back something that has been extirpated or is in the throes of extirpation.
