It’s not every day you’re called to step up in defence of your planet – but today is one of those days. A few moments ago we launched a new global campaign to change Volkswagen by turning them away from the Dark Side, and we need your help.

Despite the green image it likes to portray, VW is at the heart of a group of companies lobbying against new laws which we need to cut CO2 emissions, reduce our oil use and protect places like the Arctic from climate change.

Only a rebellion can stop them – a mass of people from all across the globe –demanding that they change. We need you to be part of that rebellion.

There's no doubt about it, Mattel is under pressure.

Your email to the CEO, highlighting Barbie's dirty deforestation habit, has shown that toying with Indonesia's rainforests is not playing fair.

Ken may have been the one to dump Barbie, but you have exposed Mattel's role in destroying rainforests for cheap packaging. Over 150,000 emails have been sent to Mattel from around the world, but now it's time for something a bit different. Hundreds of Chainsaw Barbies have been hidden around the UK, and it's up to you to track them down. Game on!

Heard the news? Ken has dumped Barbie! It's true, and not because the plastic princess has been spotted in the company of certain premier league footballers. No, it's much more serious than that. Get this: Barbie is destroying Indonesia's forests for those pretty pink boxes she likes to wrap herself in.
