If you thought Bitcoin was confusing, wait 'til you hear about 'non-fungible tokens'.



In fact you've probably already heard about them, after a major conservation charity decided to flog NFTs of pictures of tigers and the like, only to be met with the mother and father of all backlashes.



NFTs are modern and confusing, for sure. But are they really environmental kryptonite? Was the backlash deserved?



Also this week, two wonderful and separate examples of creative activism from the good folks at Greenpeace and Insulate Britain.
