In this short “explainer” video, we’re invited to take look at earth’s atmosphere and what Dan Bertalan suggests might just be the secret to life on our planet. Part One describes the role carbon dioxide plays. Even though it makes up a tiny fraction of the atmosphere, carbon dioxide plays a huge role in providing the food for life and making our planet’s temperature livable. And for over 800,000 years this tiny faction of carbon dioxide has remained relatively constant, about 300 parts per million, keeping things predictably cozy here on earth. In Part Two, Bertalan will describe how changes in the earth’s atmosphere may affect all life on our planet.

Bertalan is an award-winning cinematographer, author and graphic artist, noted for his documentary work and science education videos. He is also scientist with a love for outdoor adventure, bow hunting and storytelling. His work is prominently featured on the Into the Outdoors (ITO) Network and includes The Ottaway – A River Reborn about the Boardman River in Northwest Lower Michigan.
