Actress Dia Mirza has always been vocal about environmental issues. On the occasion of Earth Day on Thursday, she said we must hold authorities accountable for changes in the environment, too, besides making efforts on the personal front.

"We need to mobilise greater momentum now than ever before. Of course, personal behaviour change will make a difference, but along with learning to lead more sustainable lifestyles, we also need to hold governments, industry and civil society accountable. We need to imbibe and disseminate scientific facts which are now more accessible than ever before," she said.
