Coal mining Wikipedia

20191014&ensp·&enspCoal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the

20121211&ensp·&enspDeep Sea mining, like asteroid mining, is a relatively unconventional method of extracting Rare Earth elements (REEs). Unlike asteroid mining, however, deep sea mining has already been undertaken through projects such as deep sea diamond mining. Actual mining for REEs has not been attempted because of environmental issues and cost.

Using Soundscapes to Assess DeepSea Benthic Ecosystems

Targets of deepsea mining commonly coincide with biodiversity hotspots, such as hydrothermal vents. The resilience of these ecosystems relies on larval dispersal, which may be directed by habitatspecific soundscapes. We urge for a global effort to implement soundscape as a conservation tool to assess anthropogenic disruption to deepsea benthic ecosystems.
