Divya Sreedharan talks to five social and ecological entrepreneurs, both individuals and organisations, who are saving theplanet in their own little way.

What does a techie who now sets up rainwater-harvesting systems in rural schools have in common with an urban farmer who advocates growing vegetables on terraces and balconies? Can an apartment owner who composts her kitchen waste identify with a villager who stitches washable sanitary pads, or a traditional honey hunter in the Nilgiris? In a sense, they are all alike; they are changemakers. All of them are social and ecological entrepreneurs. This is how they are making a difference.
