Explanation:

South America is rich in natural resources and mining and minerals comprise a large part of the region's economy. Mining in the Amazon rainforest has become more prevalent in the last two decades, since mineral deposits in the mountains of the region have been depleted. The Amazon is home to vast mineral deposits and South American leaders, eager to channel their countries along the path of development, have granted mining rights to thousands of hectares of rainforest.
