Mining is the removal of sand, stone, gravel, and other minerals from their natural configuration, which may create environmental problems. Environmental problems occur when the rate of extraction of sand, gravel and other materials exceeds the rate at which natural processes generate these materials. The morphologies of the rivers and beaches have demonstrated the impact of mining with the ...

By systematically examining environmental impacts and adopting measures to mitigate these impacts, it is possible to make mining less destructive of the environment. Incremental efficiency gains will not do the job. Instead, an imaginative remaking of the industrial world-one that aligns economies with the natural environment that supports them is the sustainable way forward. Recycling has a ...
