Another argument supporting safe trade rules is that there are links between primate extinction and deforestation in the regions where primates are abundant, i.e. the Amazon rainforest, African rainforest, and Sumatran rainforest. Fail to prevent devastating logging in these regions, advocates claim, and a Great Ape species will likely become extinct, causing a critical link to the human past to be permanently lost. Accordingly, preventing logs from these forests from reaching foreign markets has been a major focus of Greenpeace actions, especially in 2002.
