Farming (large areas are cleared for pastoral farming. As the global demand for meat has increased many cattle farms have opened in the Amazon Basin for beef farming) Logging (tropical rainforests are cut down so that valuable trees like mahogany can be accessed and sold for timber to make furniture) Mining (the Amazon Basin is rich in natural resources such as iron ore, copper, tin, aluminium, manganese and gold. This has led to the development of mines which results in the clearance of tropical rainforest) roads (the construction of access roads for farmers, loggers and miners results in large parts of the tropical rainforest being destroyed) Population (population growth has resulted in the loss of tropical rainforest as land is cleared to build houses and infrastructure.) deforestation (destruction of trees.)
