<h3>What are the impacts of coal mining?</h3>
The burning of coal for energy produces highly toxic effluents, such as mercury and other heavy metals such as vanadium, cadmium, arsenic and lead. In addition, the release of carbon dioxide causes pollution in the atmosphere, exacerbating global warming and contributing to acid rain.
With this information, we can conclude that Sedimentation and pollution of rivers due to improper disposal of unused material would make life on the family's property unfeasible.
