Although the most recent World War ended in 1945, some places are still feeling the conflict's far-reaching effects. 

During World War II, both sides experimented with secret weapons. Unfortunately, even mysterious, confidential technology wasn't very sophisticated, and millions of dropped bombs never exploded. These battlements didn't magically disappear after the conflict ended, leading to heaps of unexploded bombs in England, Germany, and pretty much anywhere else fighting took place. 

Every year, Germany digs up around 2,000 tons of unexploded ordinances (UXOs), including a few of the biggest unexploded bombs found outside of military lockdown. 

It's startling to learn how many unexploded bombs have been found since victory was declared in Europe on May 8, 1945. An even more troubling thought comes when one considers how many more UXOs have yet to be uncovered.
