While wrapping up the 12-hour Banega Swachh India Cleanathon, brand ambassador Amitabh Bachchan said that despite differences, there was unity in what people said about cleanliness. We must introspect why the voices are not reaching the millions of people out there. We should work every day towards cleanliness and how much of the efforts are getting implemented, should also be looked into. We need millions of people who should think together to spread the message of swachhta. We must get together and think alike and inevitably become a better and cleaner nation. Mr Bachchan also thanked the volunteers participating in the cleanliness activities across the country during the cleanathon.
