Bare Bones Biology 095 – Climate Change IV

We can think of the climate as part of the physiology of the earth very similar to our own physiology that requires us to breathe in oxygen and breathe out carbon dioxide. Except that’s only half of our cycle and the rest of our breathing cycle happens outside of our bodies as part of the whole living earth. The whole of the creation is made of networks connected to networks inter-connected with more networks. It’s too complicated to understand, and so I don’t, but I’ll tell you some important facts.

First there is physiology – networks of molecules and water and hydrogen and carbon in your cells and your organs and your bodies, and also in the whole earth, all of them interacting. And they keep cycling because of energy. Human physiology and the physiology of the whole earth and all its parts are all connected. They all use food energy to do all the work of continuing the cycles of life.

Every living thing uses energy to stay alive. In all our cells, all the time, energy is released by burning sugars and other carbohydrates.

Carbohydrates are made up of carbon and oxygen and hydrogen. The energy to stay alive, food energy comes from burning the carbohydrates. Your body uses the energy and discards the carbon and hydrogen and oxygen in the form of carbon dioxide and water. These are released into the air or possibly the toilet.

Plants breathe in the carbon dioxide. They use the carbon, and then they take energy from the sun, and some water, and they put it all together to make carbohydrates. The plants breathe OUT a lot of oxygen that is left over from the process.

The plants get the water and the carbon dioxide from the air – the water comes from the earth and the clouds. The carbon comes from the carbon dioxide that we all breathed into the air.

These cycles and networks of cycles of animals and plants, and the whole earth physiology, have been going around and around and around for millions of years. They are perfectly balanced for us to live in – air, water, soil, plants and temperature. It is these networks that make our clean air, water, rich soil, and they can adapt to changes – the water and the carbon dioxide and the carbohydrates and the oxygen and hydrogen are all balanced. Sometimes they cycle together, sometimes separately, so when one bit changes the other bits also must change to maintain a viable balance. If you think of an old-fashioned watch, cycles are connected to cycles, but in living things the cycles can change themselves to adjust to changes outside themselves. Changes in the carbon cycle or the oxygen cycle or the hydrogen or water cycles must affect our climate because they make up our air, and the air interacts with the sun and the plants and animals in many different ways.

Energy is released by burning, using oxygen, like a fire in your yard, or burning in engines — burning any kind of energy source – anything that burns with oxygen produces carbon dioxide and water that go into the air and become part of our climate.

So, when we are burning and burning and burning carbohydrates from fossil fuels and also from 7 billion humans breathing out – and from coal, oil, gas, wood, dead bodies, incense, cigarettes — and at the same time we cut down the trees that breath IN the carbon dioxide – the whole vast cycle of life on earth must change or die. We don’t exactly know how it will change, and we want to know more. That doesn’t mean we don’t believe in climate change.
