Answer to Question 1
After the Amazon, central Africa has the world's largest rainforest. Forests on the Horn of Africa and in the west, including Sierra Leone and Ghana, as well as the island of Madagascar, are suffering the greatest threat. Commercial logging and clearance for agricultural purposes are the major threats. The Democratic Republic of Congo is still home to vast areas of rainforest as political instability has prevented large-scale logging.
