Bollywood power couple Ajay Devgn and Kajol have urged people to recycle and reuse plastic. The duo inaugurated the on-ground leg of `Start A Little Good` campaign and launched `Plastic Banega Fantastic` drive at Mahim creek in Mumbai on the weekend. "My heart breaks to see how plastic is littered on beaches, streets, etc. I believe in doing good for a better tomorrow. Though there is a change but the fact is things are getting worse. It`s been said that by 2050 we will have more plastic than fish in our sea and we need to do something about it. "It is about segregating plastic. It is a small thing. If we do it then plastic will be recycled and reused," Kajol told reporters at the event. Ajay Devgn said that everyone needs to do their bit for a better future. People have to act responsibly. If we speak about it some people might listen to it and some might change their thinking and act upon it as well. The CSR initiative `Plastic Banega Fantastic` is taken up by the FMCG giant Hindustan Unilever.
