Mirza spoke about her association with the cause as well as invited citizens of the city to come forward and show their support for the campaign.
This year, the theme of 'Earth Hour' is "India Unplugged", which not only calls out to people to "switch off" power, but also encourages citizens across the country to explore and adopt cleaner as well as more sustainable lifestyle by embracing renewable energy solutions.
"Earth Hour provides the perfect platform to mobilise people empowering them to contribute to the planet in their individual capacity. I am extremely proud to be associated with this campaign and would encourage others to extend their support towards Earth Hour," she said.
