Ever since the early Enlightenment, preservation and conservation have been closely related. Taken as near synonyms, their meaning is to maintain an object or system insofar as possible in its present state, to protect it from change, usually for contemplation, research, display, and perhaps for use. Conservationists who distinguish their activities from preservation emphasize conservation’s restorative aspects ― restoring a historical musical instrument, for example, or a painting, or a dinosaur, or an ecosystem. Conservationists acknowledge change but try to manage it in order to prolong a(n) _________ state. Preservationists (who may nonetheless call themselves conservationists) think of themselves more as protectors. They sometimes criticize conservationists for setting an additional priority on yield or harvest or use, rather than interfering as minimally as possible in order to preserve the original object or system, as they would do. Preservationists would, for example, prefer to keep a historical musical instrument “as found” in a deteriorated state, for study, rather than to restore or repair it for display or use.
