Call to Earth: Call to Earth: Reviving India's Waters

Our waterways often bear the brunt of modern-day human negligence. Most of India's ponds, lakes and oceans are polluted or contaminated due to human activity. Led by founder Arun Krishnamurthy, Environmentalist Foundation of India (EFI) focuses on reviving these bodies of water through a community-based conservation effort, with their work now extending into the surrounding forest ecosystems. Arun takes us on a journey across India - from the north in Delhi to the south in Chennai - for a firsthand look at EFI's most critical and ongoing projects, and the tens of thousands of volunteers that make it all possible.
