I was inspired and shamed in equal measure recently by attending the huge 'School Strike for Climate' in Oslo. "You'll die of old age, but I'll die of climate change" accused one placard. "System change, not climate change" read many more. Thousands of children thronged, chanting into the square outside Parliament to try and make their parents' generation, of which I am a member in denial, wake up and stop destroying the eco-system that enables humanity to thrive on the only planet we have access to.
