		<description>&quot;There is not much air&quot;.... Really? The air pressure at sea level on this earth is approximately 14.7 psi. That means the column of air above every square foot of earth&#039;s surface weighs over 2116 pounds. Yes, over a ton of air for each and every foot of the earths surface. Now, what is this atmosphere made of? 78% in nitrogen, a fairly inert gas. It is carried into the soil as ammonia as a result of lightning causing it to ionize. This nitrogen is the source of protein in plants (and by that definition in animals.) Legumes have bacteria on their roots that allow the fixing of atmospherical nitrogen as well. Anyhow, back to the air. Oxygen comprises about 21% of the atmoshphere. ALL of the other gasses comprise the balance.

Now, we must realize that Oxygen is a very reactive element. It is always &quot;trying&quot; to share electrons with other substances. Ie, to &quot;oxidize&quot; them. Without oxygen constantly being returned to the atmosphere, it would quickly be bound up in compounds. Life on earth as we know it would cease. So, where does the constant oxygen recharge come from?

CO2. Yep, CO2. You see, photosynthethis of plants absorbs CO2 from the air and H2O from the soil and rips the molecular bonds apart. The carbon and hydrogen are combined to form carboyhydrates. The remaining O2 is released into the atmosphere for us to breathe.

If we did manage to get the CO2 level down below 250 parts per million, plant growth would be badly stunted. If we get it down to 150 ppm, plants and us, die.

Back to the &quot;thin&quot; air. Remember, air in earth at sea level weighs 14.7 pounds per square inch. That is over 2116 pounds per square foot. That means that one square mile has over 294,953,472 TONS of air sitting on it. Now, the earth has an approximate surface area of 196,939,900 square miles. Multiply that by the tons per mile and you have an idea of the true magnitude of the atmosphere. It is an huge mass of what we call air. Our emmissions are miniscule and the plants are working all the time.

The sky is not falling. Life is not in danger of having to die from CO2 poisoning. You are in much more danger from the statists trying to destroy the western lifestyle.

I encourage you not to take my numbers for granted. Get out your calculator and encyclpedia (or use the internet). Check my numbers. Check out the equations for photosynthesis. Then, get out a history book and read what Malthus, Keyenes and Marx wrote. Look at history and science and sit down and think. Remember that facts are not exciting. But they are still facts.

Scientist are not some form of exalted persons. They are humans and live to serve themselves. They provide the &quot;results&#039; that their benefactors require. Otherwise, they are back to working slinging burgers. Always, follow the money. That is where the motivation lies.</description>

		<description>What if climate destabilization is a practical and actual result of the overconsumption, overproduction and overpopulation activities of the human species on Earth in our time? But for whatever reasons or excuses, no one is willing to talk about these human-driven threats because some imagined danger. So what? 

There are courageous people actually engaged in dangerous situations in many places on the surface of Earth this very day. Sometimes there is work worth doing that requires individuals to directly confront danger. I cannot imagine living a worthwhile life and not having to facing danger, at least occasionally. And if the cause justifies coming face to face with danger, then mere danger cannot be allowed to serve as a basis for willful blindness, hysterical deafness, elective mutism and cowardice.

Let us imagine for a moment that the current gigantic scale and skyrocketing growth of absolute global human population numbers on Earth represent the &quot;mother&quot; of all looming global ecological threats to future human wellbeing and environmental health. Would a cause like protecting life as we know it and preserving the integrity of Earth&#039;s ecology not be a cause to which people respond ably by choosing to face whatever dangers may attend such a confrontation?

Could we merely begin speaking out with a bit more precision about what are the dangers that are to be derived from the open discussion of human population dynamics and the human overpopulation of Earth? </description>
