What is the long-term trend the United States? What is the long-term trend in the Brazilian Amazon? Use scholarly (reputable) sources to answer this question.

This is important. PLEASE Use principles of economics (especially property rights, benefits vs. costs) to discuss the major causes of deforestation in the Amazon. Do not confuse the symptoms with the actual cause(s).
