As long as they don’t hurt the art (which they’re not), I think environmental activists throwing food stuff etc. onto priceless paintings to highlight the insanity of our priorities is a pretty glorious piece of agitprop.

I only mean this if the art remains unhurt! But throwing food at broadcasting towers would have none of the dramatic affect that this has. There’s a DaDa-esque surreal quality to this, a shock value that makes an excellent point: what is humanity doing to our priceless earth!?!?
