He Restored 18 Lakes and Planted 150,000 Trees in India

Bengaluru floods every monsoon season, yet struggles for water the rest of the year. Watching his city's lakes vanish beneath concrete and pollution, Harsha Tej knew something had to change.

He made a choice most people only dream about. Harsha quit his job, picked up a shovel, and started restoring the lakes that once defined Bengaluru.

Lake after lake, he cleared invasive plants that choked the water. He planted native trees that belonged in Karnataka's ecosystem, rebuilding habitats one species at a time.

The work was slow and unglamorous. But Harsha kept showing up.

Today, his BlueDot Foundation has helped restore 18 lakes across Karnataka. The organization has planted more than 150,000 native trees, creating spaces where nature can actually return.

The Ripple Effect

Restoring a lake does far more than save water. Birds that disappeared decades ago are coming back to nest. Groundwater levels are recharging, giving communities more reliable access to clean water year round.

The restored lakes act as natural sponges during monsoon season, absorbing floodwater that would otherwise overwhelm city streets. They cool the surrounding areas and filter pollution naturally.

Each lake becomes a classroom where volunteers learn how urban ecosystems can heal. Harsha's work shows that concrete jungles don't have to stay that way forever.

His mission goes beyond environmental activism. Harsha is helping rebuild the Bengaluru he remembers, where lakes were gathering places and nature existed alongside the city.

One person with a shovel proved that urban environmental damage isn't permanent.
