Many people seem to ignore or forget some parts of the cycle involved in processing energy sources. The focus is very often on the use of the material when it is converted into energy. Little attention is given to how that material is obtained (usually through violence and causing environmental damage in its extraction) and where it ends up (usually as toxic waste). This seems particularly true of nuclear.
Little attention is given to the fact that mining uranium causes damage & destruction to the environment, in addition to causing a range of ongoing health problems to humans & other species that live there. Mining uranium is also environmental racism as it occurs predominantly on lands inhabited by indigenous people, who are often not properly consulted or informed, who do not profit from the mining and are left to suffer the consequences of degraded land & waters afterwards.
