Arun Krishnamurthy quit a promising career at Google to focus on his passion for conservation based on community participation. In 2011, he founded his own NGO in Chennai, calling it the Environmentalist Foundation of India (EFI), which is active in three Indian cities. One of its most exciting programmes is the Lake Biodiversity Restoration project which has already restored 12 lakes across India. His team is comprised of some 900 volunteers, recruited through school programmes and street theatre for conservation work. Krishnamurthy will use his Rolex Award to restore Chennai’s polluted Lake Kilkattalai, allowing native wildlife to return and creating an oasis of peace that is endowed with a strong sense of community ownership.
