Recently some climate change fanatics took things to the next level and glued themselves to the tarmacs of international airports at Hamburg and Düsseldorf. While these airports are supposed to have high security, given terrorism and all that, strangely these hipsters were able to get there and do their gluing. I recall a report saying that the glue used could severely damage their hands and amputation may be required, which will limit body parts to be glued next time!
But, the real issue here is that it is far from clear that these actions do anything, for people seem more annoyed with the transport delays than anything. It is a bit like the bed-in protests of John Lennon and Yoko Ono in 1969, which got five minutes of media attention, then was forgotten.
