living things, our planet would be unlivable. For example, if living things
only took in carbon dioxide and released oxygen, the Earth's atmosphere
would support combustion much more easily than it does and even a tiny
spark could set off enormous fires. Similarly, if both took in oxygen and re-
leased carbon dioxide, life would eventually die out when all the oxygen
had been used up.
In fact, the atmosphere is in a state of equilibrium in which, as Lovelock
says, risk and benefit are nicely balanced.
Another finely-tuned aspect of our atmosphere is its density, which is
ideally suited for us to breathe.

The Atmosphere and Respiration
We breathe every moment of our lives. We continuously take the air in-
to our lungs and let it out. We do it so much that we might think of it as
normal. In fact, respiration is quite a complex process.
Our bodily systems are so perfectly created that we don't need to think
about breathing. Our body estimates how much oxygen it needs and
arranges for the delivery of the right amount whether we're walking, run-
ning, reading a book, or sleeping. The reason breathing is so important to
us is that the millions of reactions that must constantly take place in our
bodies to keep us alive all require oxygen.
Your ability to read this book is due to the millions of cells in the reti-
na of your eye constantly being supplied with oxygen-derived energy.
Similarly, all the tissues of our bodies and the cells forming them get their
energy from the "burning" of carbon compounds in oxygen. The product
of this burning–carbon dioxide–must be discharged from the body. If the
level of oxygen in your bloodstream drops to low, the result is fainting; and
if the absence of oxygen persists for more than a few minutes, the result is
death.
And that's why we breathe. When we inhale, oxygen floods into about
300 million tiny chambers in our lungs. Capillary veins attached to these
chambers absorb the oxygen in a twinkling and convey it first to heart and
then to every other part of our body. The cells of our body use this oxy-
