Environmental impact of mining Wikipedia

1 天前  Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have

When human activities lead to landslides Follow

Mining has a lot of serious effects on the environment and one such is a landslide. Mining requires man to excavate and dig up land in search of minerals or fossil fuels. This makes a huge hole in the land, most of which remains unfilled. The blasting that takes place during mining can seriously affect the land by causing vibrations.
