Mining will fragment, if not destroy habitat. It can poison waters. Some of these negative impacts are permanent. For example, there are at least 10,000 abandoned mines across Canada. This means that there is no company to take responsibility for the clean up of these mines, even when there is contamination. When there is no company that is responsible for the clean up, the government is on the hook for clean up and rehabilitation. This means that taxpayers are ultimately responsible for a mining company's mess.

Dr. Gordon Edwards gives a brief overview of risks and issues particular to uranium mining, citing regulatory changes that could make it safer. But the question still remains: should uranium mining go ahead at all?

The creation of large volumes of waste, including solids, liquid effluents, and air emissions, is a fact of life for mining and mineral processing operations. Depending on the minerals’ natural geology and how they are processed these wastes can often be hazardous to the environment and human health. Solid wastes including waste rock and tailings are, by volume, the most significant waste generated by mining and mineral processing. Solid wastes are typically in the tens to hundreds of millions of tons of waste for a single mine. A rough estimate of Canadian production is 2 million tonnes a day. Based on information available from the U.S., it is safe to assume that mining in Canada generates a greater volume of toxic waste than any other industry in the country.
