Scottish singer KT Tunstall has thrown her support behind a campaign to save Brazil's rainforest.
The Suddenly I See hitmaker has signed a petition urging Brazilian President Dilma Rousseff to reject a bill allowing loggers to cut down huge sections of the Amazon Rainforest.
The appeal reads, "To President Dilma Rousseff, we call on you to take immediate action to save Brazil's precious forests by vetoing the changes to the forest law. The world needs Brazil to be an international leader on the environment. Your strong action now will safeguard the planet for future generations."
Tunstall has posted a link to the virtual petition on her Twitter.com page, and urged her followers to join her in putting pressure on Rousseff to veto the legislation.
She writes, "Tell Brazilian President Dilma to stop the Amazon chainsaw massacre and veto the forest code! Sos Brazil."
