Sikh Environment Day commemorates Guru Har Rai Ji Gurgaddi Diwas and Sikh teachings about caring for the environment. It encourages Sikhs to help the environment through initiatives like making Gurdwaras more sustainable with solar energy and recycling, and by planting trees. The document provides examples of how some Gurdwaras have already begun environmental projects and urges readers to find ways to help their own Gurdwaras go green.
