Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.039% by volume.
As part of the carbon cycle known as photosynthesis, plants, algae, and cyanobacteria absorb carbon dioxide, light, and water to produce carbohydrate energy for themselves and oxygen as a waste product. But in darkness photosynthesis cannot occur, and during the resultant respiration small amounts of carbon dioxide are produced. Carbon dioxide is also produced by combustion of coal or hydrocarbons, the fermentation of liquids and the breathing of humans and animals. In addition it is emitted from volcanoes, hot springs, geysers and other places where the earth’s crust is thin; and is freed from carbonate rocks by dissolution. CO2 is also found in lakes at depth under the sea, and commingled with oil and gas deposits.
5 miles up the ocean
Headin‘ way back home
Struggling with that seatbelt
In sleep she is gone
Shapes foam around us
From moon to the sun
High, feeling lucky
Now I'm not on the run
We gotta burn that gas
Hope we won't touch the sea
Come on, make it fast
Set me free
Just find my sleep
In a day that‘s gone
Time makes the distance
A frozen world beneath the sun
Won't I remember
How far I'd come
Won't I remember
Now I'm not on the run
We gotta burn that grass
Hope there's no lack of weed
Come on roll it fast
