Today's award goes to an anonymous idiot in England.
A canal boat user accidentally drained [a] 200-year-old waterway - causing £3m [about US $3.9 million] worth of damage - after leaving locks open. Water ended up gushing down the Shropshire Union Canal, washing away the banks and leaving a huge gaping hole in the waterway.
Trees along the canal were torn from their roots, hundreds of fish died and boats were lifted from their moorings.
The 'human error' by an unknown Shropshire Union Canal user - thought to be on a boat or barge - will cost £3 million to repair.
. . .
About 15 boats were stranded and more than 10,000 fish were rescued, but many more died when they were washed on to dry land.

I hate to see that. English canals are very historic, dating back to before the Industrial Revolution (which could not have taken place without them). Today, so-called "narrowboats" are a very popular form of recreation and leisure travel. Here's another part of the Shropshire Union Canal, showing what it looks like when idiots don't mess up (image courtesy of Wikipedia).
I'm sure this incident ruined their planned summer vacations for many people. Hopefully, things will be back to normal by next cruising season.
