In Northeast India next to the Brahmaputra River sits Majuli Island, a giant sandbar that happens to be the largest river island on Earth, home to 150,000 people. It is also the location of the 1,360 acre Molai Forest, one of the most unusual woodlands in the world for the incredible fact that it was planted by a single man. Since 1979, forestry worker Jadav Payeng has dedicated his life to planting trees on the island, creating a forest that has surpassed the scale of New York's Central Park.
