De-nature means to remove natural qualities or characteristics from something. The antonyms for de-nature are "naturalize" and "re-nature." Naturalizing refers to making something more natural or returning it to its natural state. This process often involves reintroducing native plants and animals, reducing human activity, and restoring habitats. Re-nature means to reverse the process of de-naturing, returning something to its original, natural state. This can involve removing pollutants, replanting vegetation, and reintroducing wildlife. De-naturing can have negative consequences for ecosystems and the environment, so naturalizing and re-naturing are important strategies for conservation and restoration efforts.
