Priyanka Chopra today cleaned the Yamuna river here in a symbolic gesture as part of an initiative to create awareness for environmental issues.

Wearing oversized sunglasses and a white kurti, the 29-year-old star picked up a mason's fork and cleaned the floating rubbish from the bank of the Yamuna at the Dussehra ghat, with the iconic Taj Mahal in the backdrop.

The event kickstarted the fourth NDTV Greenathon campaign, of which Priyanka is the brand ambassador.

"This time we began our campaign from Agra because tourist inflow is maximum here. Taj Mahal is on the bank of river Yamuna, which has become a dumping zone of waste materials now. If we do not protect our environment our future will be dark," Priyanka said.
