It’s gotten by felling trees.
It takes more than 15 years for a fresh plant seedling to mature into a tree.
As a result, replanting cut-down trees takes a long time.
Cutting down trees depletes forests, resulting in an ecological imbalance.
Use of wood as a source of energy is not a sensible idea due to inappropriate air and the aforementioned reasons.
Final answer:
Hence, the use of wood as a fuel is not a wise decision.
