It’s not viable. The amount of resources mined from Earth is up from 39.3 billion tons in 2002. A 55 percent increase in less than 20 years. This puts Earth’s natural resources under heavy pressure. We are already extracting 75 percent more than Earth can sustain in the long run.
Mining has been a part of the Earth’s history since prehistoric times. Mining has played a role throughout the millennia - from Neanderthals’ use of stone, to ancient Egyptians’, Greeks’, Romans’ and Incans’ more sophisticated mining processes and uses of mined materials. From the Industrial Age and the ability of mass production, societies’ progress has led to our Modern times ...
Mining depletes finite resources and in a strict sense, therefore, is inherently unsustainable. For instance, there is only a finite amount of copper in the earth’s crust, and each unit of copper extracted increases the fraction of the total copper resource base that is in use.
The mining of earth’s natural resources is, there fore accelerating, and it has accompanying environmental consequences. ADVERTISEMENTS: A mineral is a pure inorganic substance that occurs naturally in the earth’s crust.

pollution that has a single, identifiable source. resources that can be recycled or replaced within anywhere from a few days to several hundred years. the ability to maintain resources at a level that can support life in the present and in the future. the maximum rate at which humans can use a renewable resource without depleting the resource.
C. The once-leaking pipes that transport wastewater from the mining pits to waste ponds have been reengineered to be leak-proof using carbon nanotubes. D. A makeover of $1 billion will allow for recycling of wastewater and most chemicals used in mining. E. The mine is closed after being outcompeted by competition from China.
The human society has profited from exploitation of earth resources, precisely when energy use became much more efficient during the industrial era. Some of these earth resources (renewable and non-renewable) are oil and gas, coal, water, metal ore, wind, air etc. and their methods of exploitation are surface and subsurface mining methods .
Students will analyze the quantities and origins of basic mineral resources. NGSS:MS-ESS2-1 – Develop a model to describe the cycling of Earth’s materials and the flow of energy that drives this process. • Students will explore mineral resources used in their lives and learn the origins of
Mineral resources are essential to life as we know it. A nation cannot be prosperous without a reliable source of minerals, and no country has all the mineral resources it requires. The United States has about 5 percent of the world’s population and 7 percent of the world’s land area, but uses about 30 percent of the world’s mineral ...
