If you could describe the sweet smell of success then perhaps this time, just this once, it would smell like a Big Mac. Thanks to enormous pressure from thousands of our supporters from around the world (and that means you), McDonald's has agreed to stop buying chicken fed on soya grown in deforested areas of the Amazon rainforest in Brazil. Now we really are loving that.

Thousands upon thousands of emails and letters were sent to their European headquarters, and these have been directly responsible for this amazing result so an enormous thank you to everyone who took part. We were hoping to reveal all in last month's newsletter but negotiations went on longer than expected, so better late than never!

The campaign has been so successful that not only have McDonald's made their own pledge, with our help they've been instrumental in getting other food companies and supermarkets, such as Marks & Spencer, Sainsbury's, ASDA and Waitrose, signed up to a zero deforestation policy as well. But it goes even further than that, and pressure from all these companies has forced their suppliers, the big multinational soya companies such as Cargill, to come to the negotiating table.

The result is a two-year moratorium on buying soya from newly deforested areas and, given that our campaign only began in earnest in April, this is a fantastic achievement. The campaign has been a perfect example of what Greenpeace does best - mobilising our supporters around the world so companies, governments and other decision makers are only too aware that we all want a greener, more peaceful world, so thank you once again.
