I thought that the real environmental problem comes from acid mine water discharge. This problem becomes very serious when large quantities of sulphide rock are bought to the surface. The broken sulphide rock which is highly acidic, leaches the acid when it comes into contact with water. The highly acidic run-off then leaches metals from surrounding rocks and deposits this poisonous mix into watercourses where it destroys all forms of animal and plant life. Old mine sites that are covered in tailings dumps, open cuts and old shafts are the culprits. I understand that Canada has a major problem with this type of pollution. I think the greenies probably confuse the two types of pollution, for example cyanide has an immediate effect on aquaculture, where very small quantities in the water will kill all the fish (until the cyanide is gone). The acid mine water discharge stays to pollute forever. What are the Canadians doing to address the problem of acid mine water pollution?
