British actor Sienna Miller teamed up with Bollywood star Amitabh Bachchan on Tuesday to urge Indians to do more to slow global warming.
The actor met Bachchan in Mumbai on Tuesday at the start of a weeklong trip to India as an ambassador for Global Cool, an organization that spreads awareness about global warming.
Miller said people could help by turning their air conditioners down by even one degree or by turning off phone chargers and other electronic equipment when it's not being used.
``If each one of us does our bit, we will be helping to keep global warming from harming our countries,'' she said.
Bachchan announced that the Indian International Film Academy would partner with Global Cool to increase knowledge about greenhouse gas emissions.
``Carbon emissions will be huge from countries like India and China with growing populations and economy,'' said Bachchan. ``It will be wise to start doing whatever we can to protect our planet.''
Miller, 25, acted in the films ``Casanova,'' ``Layer Cake'' and ``Alfie.''
