What resource can be replaced at a sustainable rate?

A resource that can be replaced at a sustainable rate is timber from well-managed forests. When trees are harvested responsibly, and new trees are planted to replace them, the forest can continue to provide wood indefinitely. This practice ensures that the ecosystem remains healthy, supports biodiversity, and maintains carbon sequestration benefits. Sustainable forestry practices, such as selective logging and reforestation, are key to achieving this balance.
