Today, you may have eaten your favourite chocolate bar. A lovely mix of milk, cocoa and fat. Turn the packaging and have a look at everything that is in the chocolate bar. Take a minute to guess which products may have been needed to produce what is written on it, and where these products may come from. Any idea? For example, the cows who produced the milk may have been fed with soy from South America, the cocoa probably comes from western Africa, while the fat may directly come from some palm oil plantation in South-East Asia. In all of these places, the production of these agricultural commodities may be linked to deforestation, and the degradation of savannahs, wetlands or other ecosystems. Now, project yourself back 40 years ago. Where did the products of your chocolate bar come from at that time? Did it generate more or less pressure on ecosystems than nowadays?
