Barbie "hearts" recycled paper. Mattel, owner of the iconic toy, has this week bowed to pressure from environmental groups and will stop buying any paper or packaging products from its current controversial supplier, Asia Pulp and Paper. Instead the company has pledged to use recycled packaging. It's another blow to APP, which has been labelled by critics as one of the most environmentally damaging companies on the planet - who accuse it of mass deforestation across Asia. On the latest One Planet show - rather than interviewing Barbie - we get a rare interview with Aida Greenbury, managing director of APP.

Also in the show, as US supercop Bill Bratton arrives in the UK to advise the government on how to deal with gang culture in the wake of the summer riots, One Planet walks the streets of London with Professor Wouter Vanstiphout to discuss how urban planning could have helped prevent the social unrest.

Plus we get a round-up of the environment news - including an update on the cargo ship grounded off New Zealand.
