ecotard
Someone so enamored with ecology that they cannot understand common sense or reality.
Example; Ecotards = idiots that burn down wood-frame buildings under construction to protest environmental policies. This irresponsible and short sighted act, not to mention being highly illegal, puts innocent lives at risk, wastes forest products that it would appear that they would want to protect, causes air and ground water pollution, causes increased insurance costs to the entire building industry and related increased building costs to society as a whole. These are some of the issues that an Ecotard does not comprehend in their single-minded and ill-conceived quest to "protect" the environment.
