One of my earliest childhood memories is marching against the apocalypse with my parents. It was Vancouver in the mid-?80s. I was around 10 years old?the age my son is now?and very anxious about the end of the world. (Around the same time, my parents had, perhaps foolishly, let me and my older sister watch The Day After, a TV movie set in the wake of a nuclear holocaust.) With Cold War tensions between the US and USSR pushing the Doomsday Clock toward three minutes to midnight, annual peace marches brought hundreds of thousands downtown demanding nuclear disarmament.
Back then, it was easy for people of all ages to grasp the possibility of World War III?a pair of powerful men could end humanity instantly with one misunderstanding and two turned keys. Today?s climate crisis, on the other hand, is a slow-motion apocalypse that we?ve known about for decades?the term ?global warming? was coined way back in 1975, the year I was born?yet kids are somehow far more capable than grown-ups of comprehending the coming threat.
