At 13, Neha Blunt is using code, creativity and community action to tackle one of the world’s most urgent environmental challenges.

The New Jersey student created Water Saver, a web application that turns everyday conservation into an interactive challenge, helping households track their water use and make practical changes.

Her wider campaign has educated more than 1 million people worldwide, encouraged over 100,000 residents to change daily habits and contributed to an estimated 20 million gallons of water savings.
