Although there are temperate rainforests, questions in the GCSE geography are usually about the tropical rainforests as they are so important to the well-being of our planet. Your studies should enable you to discover how humans use this incredible resource and the reasons behind it. You also need to know the possible benefits and drawbacks.
Humans have been exploiting the tropical rainforests for thousands of years but the problem is that during the twentieth century, globalisation led to a huge increase in demand for products from rainforests. Also, the discovery of valuable minerals (e.g. gold) meant that countries could export these, earning foreign exchange and paying off debts to other countries. These minerals could also be used in local industries to increase their output and help towards becoming a MEDC.
