Another day, another mass walk-out from schools around the world, including throughout Australia, by children protesting about their elders’ inaction in the face of a climatic calamity that’s set to wreck their futures (apparently).

This latest children’s crusade is a brainchild (no pun intended) of a 15-year old Asperger version of Pippi Longstocking, a little budding totalitarian called Greta Thunberg, who has built her protest into an international movement from the unpromising beginnings of a one-girl sit-in in front of the Swedish Parliament.
