If you're in London town this weekend why not indulge your sweet tooth and head down to the Chocolate Festival on the South Bank. The RSPB team will be down there with our Sumatra stand and stocks of our "guilt-free" Love Nature chocolate.

Ok so it's not completely guilt-free because I'm afraid we haven't cracked calorie-free chocolate yet.However, you can treat yourself safe in the knowledge that what you're eating is good for the rainforest in the sense that it doesn't contain any soya or palm oil, proving that it's possible to make something scrummy without the ingredients that threaten our tropical rainforests. So when the choccie cravings hit, eat something sweet for Sumatra.
