The Mithi River doesn't have it easy. It originates peacefully from the Powai and Vihar lakes. But then before it flows into the Arabian Sea at Mahim Creek, it crosses through the industrial areas of Kalina and Kurla, where industrial waste is spewed into the water body, clogging it up like the arteries of a chain smoker.

This waste is detrimental not only to the river itself, but also spills out onto the Dharavi and Mahim beaches. That's why a youth community called Beach Please is trying to get to the root of the problem, and is organising a clean-up drive on Mithi River this Sunday as part of a sustained process.
