---The Carbon-Oxygen Cycle
Carbon dioxide has always been a component
of our Earth’s atmosphere. We learned about the carbon-oxygen
cycle in school. Carbon dioxide is absorbed by plants and
used, along with sunlight, to form the building blocks of plant
life. That process, called photosynthesis produces oxygen as
a byproduct. People and the animal kingdom use that oxygen
from the atmosphere and replace it with carbon dioxide as we
breathe and live. When common organic matter (wood, leaves,
grass, etc.) decomposes or is burned, that also takes oxygen out of
the atmosphere and adds carbon dioxide. Since humankind
discovered how to burn coal and oil to produce useful heat and
energy, especially recently, the amount of carbon dioxide in our
atmosphere has been increasing.
Running out of oxygen for people and
animals to breathe is not expected to be a problem any time
soon. The problem is that carbon dioxide is one of those
gases in our atmosphere, which does not let the warm Earth radiate
its extra heat on out into space. It reflects the heat waves
back down to the Earth’s surface. Temperature measurements in
thousands of locations indicate that the average temperature of the
Earth’s atmosphere has been rising. The Earth needs for us to
reduce the carbon dioxide going into the atmosphere.
