World Wars I and II destroyed cities in huge urban areas, yet many of these cities were rebuilt within 20 years. The difference between these catastrophes is due to the fact that while the environmental landscape in cities destroyed by conventional warfare stayed relatively healthy, cities which were impacted by nuclear radiation will remain partly or completely uninhabitable for centuries. Within the “controlled” environment of a nuclear plant facility, spent fuel rods should be kept in a safe place for 100,000 years, and the 250,000 tons of radioactive waste produced worldwide will remain dangerous to all life for thousands of years. I have never thought of such a long time-span which could well extend beyond humanity’s existence on Earth. This new discovery is what I and many of my readers share.
