What are the opposite words for use up?

The antonyms for "use up" can be "conserve" or "save." To conserve means to use something carefully and wisely to avoid waste or depletion. Saving, on the other hand, refers to keeping something for future use or preserving it from loss, damage, or destruction. Both antonyms represent actions that promote resourcefulness and sustainability. By conserving or saving resources, we can reduce our carbon footprint and lessen our impact on the environment. Instead of using up all our energy on wasteful activities, we can adopt a more responsible approach and make a positive difference for the planet.
