Co2 is the air. A quilt 3.2 meters thick!

Human beings adds around 70 million tonnes of invisible carbon dioxide (CO2) to the atmosphere every day! Unfortunate fact is that Co2 is invisible, odorless and mixes with the air. Hence we don't seem to feel the impact. All the carbon-dioxide in the air in 2008, were it not to get mixed and end up creating a separate layer, it would be a quit across the globe with the thickness of over 3.2 meters. Scary. isn't it!
