MONROVIA, Liberia (AFP) — A recent investigation by the non-governmental organization (NGO) Global Witness has revealed that some of the world’s most renowned chocolate brands, including Mars, KitKat, and others, may be contributing to deforestation in Liberia’s Upper Guinean rainforest. The report, published on Tuesday, highlights the environmental impact of cocoa production in the region, despite many companies’ claims of sustainability.
