Climate Activists Continue to Vandalize Famous Artworks.

Climate activists are using a new method to draw attention to their cause by throwing paint and food at famous artworks, including da Vinci's "Mona Lisa" and Van Gogh's "Sunflowers." The protests are meant to demand action on climate change. Museums are increasing security measures, such as implementing "zero bag" policies and placing more artwork behind glass, to prevent damage to the art. The tactics have so far limited damage to the art, keeping the most severe criminal charges at bay.
