On World Environment Day on Wednesday, Bollywood celebrities, including Akshay Kumar, Dia Mirza, Anushka Sharma and Varun Dhawan, urged the people on social media to take care of the environment by avoiding plastic and planting more trees.

Actress Dia Mirza, also a UN Goodwill Ambassador for the environment, explained people about the importance of plantation. "Trees are natural air purifiers and sequesters of carbon! As we celebrate World Environment Day with action -- planting indigenous trees -- we hope more people will come together to beat air pollution," she wrote.
