2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as the result of mining).

2. Longwall mining. In longwall mining, the setup is like a subway train, except at the back of the train, there is a mechanical digger (shearer) that breaks the ores into pieces as it rotates. The broken pieces of ore are caught in the train (conveyor) which brings the ores outside the mining site. The longwall is the subway which contains the shearer and the conveyor.
