w h a t i s a i r? we share the air … the air itself is a biological product … a result of active exchange of gases with living organisms. The air is a protective skin, a warming blanket, an exchange & water circulation medium…
w h a t i s a i r? we share the air …the composition of the air seems to violate the ordinary rules of equilibrium chemistry. James Lovelock GAIA – The practical science of planetary medicine
w h a t i s a i r? we share the air nitrogen 79%
w h a t i s a i r? we share the air nitrogen maintains our atmospheric pressure nitrogen 79%
we share the air over billions of years CO 2 extracted from atmosphere carbon stored as chalk, limestone & fossil fuels result – an atmosphere for life to evolve and prosper. where has the CO 2 gone?
we share the air n a t u r e c a nt c o p e Oceans & forests cant absorb all the CO 2 from our cars, planes, homes & factories.
we share the air n a t u r e c a nt c o p e Thats why CO 2 is increasing in the atmosphere so fast
we share the air n a t u r e c a nt c o p e …and the earth is now warming
