Mankind needs a slap upside the head about the seriousness of man made global warming. That was their intention. It's what protests do. Like the dumping of the tea in Boston Harbor. Their intention is not to harm the art.
The art was not harmed. Of course some media outlets never mention that. They knew the art was protected. What is not protected is all life on earth from man made global warming/climate change. The outrage should be there not on some trivial painted thing. We are ignoring the problem. I support their actions. I think protest is fine and in fact good for society. Art has always been a way to understand things. Sometimes the tea must be dumped.
