ore mining impacts on the atmosphere

Amazon mining | WWF

The Amazon is considered to have great potential for mineral assets, namely copper, tin, nickel, bauxite, manganese, iron ore and gold. As a result, governments are providing tax incentives for large-scale projects, in order to boost development. As extractive technologies improve, it is likely that the scale of Amazon mining will increase.
