A classroom air filter that pulled pollution readings down from about 160 to 98. Diyas — small festival lamps — redesigned to be biodegradable and oil-free so they stop polluting the Godavari River. A school drive that collected nearly six tonnes of waste paper for recycling. These are among the 15 finalists of the first I CAN Earthshot Challenge, which reached close to one million students through more than 15,000 schools across 24 Indian states, inviting children aged 9 to 17 to solve a real environmental problem in their own community.
