In 1989, I hosted a CBC radio series, It’s a Matter of Survival, featuring interviews with almost 150 scientists and environmental experts from around the world. Their warning was consistent and stark: Human beings were causing unprecedented changes to Earth’s systems, the detrimental effects were already taking shape, and people would need to reinvent how we live, consume, use energy and move around in order to avoid a looming global crisis.
The public response was impressive. In this pre-internet era, the CBC received 16,000 handwritten letters from listeners eager to act on climate change and other environmental issues. (This would eventually lead to the David Suzuki Foundation’s creation.)
That was 30 years ago.
