Today, hundreds of thousands of young people are responding to a global crisis - that of climate change and ecological collapse. In the 1930s, the world also faced a global crisis - the rise of militant imperialist and racist ideologies, in particular the rise of Nazi Germany, Fascist Italy, and Imperial Japan. Then, in World War 2, in the 1940s, hundreds of young men and women – including Canadians - became secret underground agents and risked their lives to defend freedom in Europe and in the world from Nazi racism and tyranny.
