I know this is an old video, but I just can't get enough of it.
I know there are people who think this woman is brilliant, who want to vote for her, and think she will make a good President.
Michelle Bachmann is an amazing example of just how stupid Americans have become. She is convinced that if she says "the world is flat" enough times, then the world will be flat. So she keeps repeating that carbon dioxide is not dangerous, and eventually everybody will believe her. Well, those people who think the world is flat, like the people of Minnesota!
If you look at the periodic table above, you will see that carbon (C) and oxygen (O) are both natural elements, so that means that CO2 must be twice as safe as anything else in nature, like methane, for example.
Here is an excerpt about carbon dioxide that appears to be non-partisan (that is, it does not appear to be presented by anybody that opposes the tea party):
Carbon dioxide and health
Carbon dioxide is essential for internal respiration in a human body. Internal respiration is a process, by which oxygen is transported to body tissues and carbon dioxide is carried away from them.
Carbon dioxide is a guardian of the pH of the blood, which is essential for survival.
The buffer system in which carbon dioxide plays an important role is called the carbonate buffer. It is made up of bicarbonate ions and dissolved carbon dioxide, with carbonic acid. The carbonic acid can neutralize hydroxide ions, which would increase the pH of the blood when added. The bicarbonate ion can neutralize hydrogen ions, which would cause a decrease in the pH of the blood when added. Both increasing and decreasing pH is life threatening.
Apart from being an essential buffer in the human system, carbon dioxide is also known to cause health effects when the concentrations exceed a certain limit.
The primary health dangers of carbon dioxide are:
- Asphyxiation. Caused by the release of carbon dioxide in a confined or unventilated area. This can lower the concentration of oxygen to a level that is immediately dangerous for human health.
- Frostbite. Solid carbon dioxide is always below -78 oC at regular atmospheric pressure, regardless of the air temperature. Handling this material for more than a second or two without proper protection can cause serious blisters, and other unwanted effects. Carbon dioxide gas released from a steel cylinder, such as a fire extinguisher, causes similar effects.
- Kidney damage or coma. This is caused by a disturbance in chemical equilibrium of the carbonate buffer. When carbon dioxide concentrations increase or decrease, causing the equilibrium to be disturbed, a life threatening situation may occur
