Trees and Our Lives
Trees give us: Oxygen (one tree = oxygen for 2 people for a year), Food (fruits, nuts), Medicine (neem, tulsi, ashwagandha), Timber (furniture, buildings, paper), Shade and coolness (cities with trees are 3-5ยฐC cooler!), Biodiversity (one oak tree supports 500+ species). Deforestation: India lost significant forest cover. Reforestation: India planted 66 million trees in 12 hours (2016 record). Plant a tree today!
