Plants ( trees , shrubs , flowers ) absorb CO2 ( photosynthesis ) and emit OXYGEN - humans and animals must breathe oxygen to survive - fire requires oxygen to propogate , releasing CO2 from the combustion of fuels . It's all part of the Carbon Cycle ( kinda like a dog chasing it's tail ) - mesh that with the Menstrual Cycle and we have a Bona - Fide dilemma on our hands . Think before you dink , and learn before you burn ! Included below are the lyrics of on of my favorite songs by Bill Kirchen ( singer and guitar player for Commander Cody and the Lost Planet Airmen ) . Couldn't find a decent free download of the song to link to , my copy is from a Internet MP3 pay site . Well worth the money - Rocks into Sand by Bill Kirchen !
Long before fish every walked on land, Time was turning rocks into sand. Rocks into stone, stone into sand, Sand that slips through the hands of man
So I built my castle close by the shore And I slept by the sounds of the ocean's roar. Then I came to understand That my house was built on shifting sand
So we went to the hills and built us a town With beautiful views for miles around. When the mountain shook and tumbled down We knew we built on shaky ground.
