IRS officer Rohit Mehra and his wife Geetanjali noticed that Delhi's kids were losing their connection to nature. To fix this, they started the School of Trees, a free weekend "tree party" in a local park. Instead of boring books, children learn by making seed balls and playing games that explain how nature works. This helps the community by turning kids into eco-heroes who plant trees and teach their families how to compost and recycle at home.
