Kangana Ranaut has donated ₹42 lakh towards 'Cauvery Calling', a campaign by Isha Foundation which will help plant 1 lakh saplings across Cauvery basin and help farmers introduce agroforestry in an attempt to replenish the river's ecosystem. "People who can must donate at least two saplings," she said. Actresses Kajal Aggarwal and Tamannaah Bhatia also joined Kangana for the initiative.
