Which material can be considered a renewable resource if managed properly?

Timber is considered a renewable resource because it comes from trees, which can be replanted and regrown over time. If managed sustainably, forests can be harvested for timber without depleting the resource. This involves practices such as selective logging, ensuring adequate regrowth, and maintaining the ecosystem's balance. Unlike fossil fuels, minerals, and metals, which are finite resources that take millions of years to form and cannot be replenished on a human timescale, timber can be produced continuously if the harvesting process is properly managed. This makes it a key material in sustainable building and manufacturing practices.
