A person who advocates for or works to protect natural environments, wildlife, and natural resources from destruction or overuse.
From 'conservationism' plus the agent noun suffix '-ist,' which denotes a person who practices or believes in something. The term became widely used in the early 1900s for environmental advocates.
Modern conservationists use science, policy, and technology, but the word echoes earlier meanings of 'conservator'—the timeless human impulse to be a guardian of natural treasures.
