An activist rapper in Kodaikanal took on corporate giant Unilever and won big!

"Unilever clean up your mess." Viral rap video slams giant company for failed clean up.

An Indian rapper has gone viral with a music video calling on consumer products giant Unilever to clean up alleged toxic waste from a forested southern hill station.

Sofia Ashraf's video, posted online by a nongovernmental organization called Jhatkaa, or "shock" in Hindi, has had more than a million views on YouTube, drawing attention to accusations against a thermometer factory in the town of Kodaikanal that closed down 14 years ago.

Hindustan Unilever, the Indian subsidiary of the consumer goods company, has denied wrongdoing. It disputes claims of former workers who say their health has been damaged by exposure to mercury. (More: REUTERS).
