36. Do not burn firewood excessively.
•Burning of wood produces a lot of smoke which
is very harmful for human being.
•When trees are cut down to obtain wood for use
as fuel, then all the useful substances which are
obtained from trees are lost.
•Deforestation is very harmful for environment.
37. Practice eco-forestry
❑ Eco-forestry is a restorative method of forest
management, which is not based on economic
productivity.
❑ In this practice, certain trees are selectively
harvested while causing minimal damage to
the rest of the forest.
