It all started with the first Earth Day. At least that’s where I personally think the environmental movement really made its first, very public mark. Maybe you remember that day in 1970, maybe not. I was a high school junior back then, and I remember the emphasis on planting more trees and recycling cans and bottles. The spirit of Earth Day has grown enormously and morphed quite considerably. Now we tend to talk about climate change and sustainability. And while most of us have some knowledge in this area, we can be bit shallow on the subject. Yes, I’ll raise my hand first. I get it, but don’t press me for too many details.
