Bollywood superstar Amitabh Bachchan has joined forces with British actress Sienna Miller to advise Indians to go green.
Bachchan met the Factory Girl star, in Mumbai on July 17 and spoke about doing his bit to protect the earth.
The Bollywood icon had earlier announced that the Indian International Film Academy (IIFA), of which he's a leading member, will collaborate with Global Cool, an organisation that spreads awareness about global warming.
"Carbon emissions will be huge from countries like India and China with growing populations and economy. It will be wise to start doing whatever we can to protect our planet," Contactmusic quoted him, as saying.
Miller, who is in India for a week-long trip as an ambassador for Global Cool, also showed her support for the cause.
"If each one of us does our bit, we will be helping to keep global warming from harming our countries," she said.
