Forests also provide livelihoods and food for forest dwellers, contribute to social and economic development, and offer environmental benefits such as rainfall regulation, air purification, and habitat preservation.
(3) Elaborate the remedies for forest conservation.
(3) Remedies for forest conservation include enforcing laws against illegal logging, promoting afforestation and reforestation programs, increasing public participation in forest conservation initiatives like Van Mahotsav and Social Forestry, raising awareness about environmental conservation through education and media campaigns, and conducting research on forest management practices.
