Bindi Irwin takes on toilets Environmental crusader Bindi Irwin has signed up as a celebrity spokesperson for GrimeStoppers. AFTER tackling the big-ticket issues of over-population and birth control, Bindi Irwin is now putting her weight behind toilet hygiene. The teenage environmental crusader has been named as the ambassador of GrimeStoppers, a campaign to get the federal government "to provide hygiene legislation for schools." In other words, the 15-year-old wants all schools and public spaces to be equipped with soap. "At the moment government legislation does not require public schools to have soap in their restrooms, which I think is really sad," Irwin says in a new video message promoting the campaign. So I think it's really important to encourage kids to wash their hands after using the bathroom, before returning to school. The initiative comes from the Children's Global Hygiene Foundation, which will attempt to break two Guinness World Records on Global Handwashing Day on October 15. The first step is to get the most number of people from different nationalities to wash their hands in one location, and the other is to get the most number of people washing their hands in numerous locations at once. Earlier this year, Irwin made headlines when she spoke out after an essay she penned on the threat of over-population and the need for birth control was heavily edited by US authorities.
