Yet there are places which have been geologically stable for 100's of millions of years or more. Change does happen but the risks can be made negligible compared to the various risks associated with other sources of energy. The damages of worse case nuclear waste leakage would also likely be very localized and manageable. Meanwhile fossil fuels have enormous environmental impacts across huge areas. Even solar and wind have large ecological impacts and aren't (likely) capable of replacing fossil fuels in time to prevent potentially catastrophic effects from global warming. It's all about weighing the risks.
