Above are 3 examples of the many pieces of  “art” produced by just one person across 10 national parks right across the western United States. Unsurprisingly, the National Parks Service has issued a press release saying “Vandalism is a violation of the law and it also damages and sometimes destroys often irreplaceable treasures that belong to all Americans.”

On the other hand, here are some of the temporary artworks the UK’s National Trust has willingly allowed, including in a National Park:


Are both organisations right? Or just one of them? Would the US National Parks Service agree with the UK National Trust that if it’s temporary and for a good cause it’s OK and won’t invite damaging copycatting”? Or not?
