Sir Paul McCartney has spoken out in disgust at Australia's plans to cull a large number of kangaroos. The former Beatle has added his support to a campaign by Vegetarians International Voice for Animals (Viva!), who are desperate to halt the proposed killing of 500 of the marsupials near the country's capital, Canberra. The animals have been targeted to be culled after the Australian government issued reports stating their large numbers impacted heavily on other species in the area. The 65-year-old rocker, who has been an avid campaigner for animal rights, says, "There is an urgent need for action to protect kangaroos from a barbaric industry which slaughters them for meat and leather." VIVA! have long fought a battle against the killing of kangaroos for meat exportation. MCCartney's latest comments come just after the release of a new People For the Ethical Treatment of Animals (PETA) poster campaign in which he describes the moment he decided to become a vegetarian.
