Is mining bad?

The three major components of mining (exploration, mining, and processing) overlap somewhat. After a mineral deposit has been identified through exploration, the industry must make a considerable investment in mine development before production begins.

What is the best type of mining?

The main impact of mining and oil development on these ecosystems is the alteration of the water regime, especially lowering of the water table and depletion of groundwater. These impacts may result in increased salinization of the soil and erosion, which eventually lead to a decline in vegetation and wildlife species.

The use {of modern|of recent|of contemporary} molecular biology {to modify|to switch|to change} microorganisms genetically for processing {applications|purposes|functions} {should be|ought to be|must be} pursued as “blue-sky” {research|analysis}.

What is the synonym of mining?

Mines are known to cause severe environmental problems. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes.
