The Mona Lisa is arguably the most famous artwork and possibly the most valuable artwork on the planet. It is most likely to have a security screen capable of deterring any vicious and sustained cake attack so, as an attempt to do damage it was rather feeble and dim-witted but as a publicity stunt for the cause of climate change awareness, it has been a mini-stroke of genius and, as a plus, we are so much more aware of cake than ever before. Environmental awareness is vital to sustaining our environment for human life, it is not for the sake of the planet, the planet will go on unconcerned, uncaring ad indifferent with probably a sigh of relief when humanity finally dies out or moves on to other planets. Applaud the cause and prosecute the attacker for their crime.
