C02 is an essential colourless odourless gas...
And we humans, our machines and factories emit a staggering 1-1.5% of the worlds C02.

"Colourless odorless" was exactly how chloro fluorocarbons were described by dupont but they still knocked a great big hole in the ozone.
1-1.5 % ? Where did you get that number from?
