Concept:Forests are renewable, so over-exploitation becomes a problem when they are not replenished.
Explanation:Forest resources can naturally regenerate over time.
This happens only when they are used sustainably and allowed to regrow.

This leads to deforestation, loss of biodiversity, and long-term resource depletion.
Therefore, the major problem arises from the failure to renew the resources.
