NASA recently released a video, A Year in the Life of Earth’s CO2, a super computer model that shows pollution in action. I’ll admit I thought it would be boring or obvious, but the imagery drew me in immediately, and I learned a great deal about both carbon dioxide and carbon monoxide pollution, its sources and how it spreads globally. It’s just three minutes long and includes good music and compelling graphics. I had no idea pollution could look so pretty, well in a graphic that is, in our lungs and in the our atmosphere? Not so much.
