Quiz - taking our breath away

Updated on February 9, 2018

Where to For Air?

So many take the air we breathe for granted. Lungs automatically draw in air, they get their fill, the cells get rejunenated with oxygen and we go on our merry way? Right! WRONG!

The air we breathe is foul and becoming more so daily. The massive thunderstorms and floods hitting the southeast of Australia are not helping. So what happens when our breathe is taken away? Do we carry gasmasks? This lens deals with why we have to breathe and why it is becoming harder.

During a heat wave in Canberra, Australia, recently let me tell you it was hard to breath. Checking with people in Sydney and elsewhere they reported the same problem. You get the feeling that there is simply not enough oxygen and the body is suffering

That is why I decided to have a closer look and do this lens,

Composition of Air

It is time to examine this question in relation to what we are breathing in.

The nornmal composition of air is in percentage units:

Oxygen 20.95

Nitrogen 78.09

Carbon Dioxide 0.03

Hydrogen 0.00005

Argon 0.933

Neon 0.0018

Helium 0.0005

Krypton 0.0001

Xenon 9 10-6

Now what happens if and when the oxygen levels drop and carbon levels increase? So I ran this question through the SE and this site came up,

"According to a study conducted by scientists from the Scripps Institute there is less oxygen in the atmosphere today than there used to be.

We are losing three oxygen molecules in our atmosphere for each carbon dioxide molecule that is produced when we burn fossil fuels. Studies of ice cores and recent data from direct atmospheric sampling have shown that there has been a 30% increase in carbon dioxide since the beginning of the industrial age"

Scientific Observation of Carbon in the Atmosphere

When fossil material burns there is smoke, which consists mostly of carbon.

It combines with oxygen in the air to form CO2, which is a dangerous gas for animals. For every carbon atom there are 2 oxygen atoms required to form the gas. That depletes the atmosphere of oxygen for that reason. Fossil material is anything that was once alive, e.g. trees, plants and animals. Long buried ancient forests are largely the source of oil and gas

Scientists are at odds to explain whether this is bringing about global warming and climate change. Some believe that a layer of CO2 surrounding the earth is keeping the heat in and consequently warming occurs. Others believe that a layer of carbon, such as that emitted from aircraft, is shading the earth from the sun and will cause global cooling. It is hard to get a concensus, therefore, as we all have different opinions on the matter.

This is a snippet from one paper on the subject: "During the past 50 years, atmospheric CO2 has increased by 22%. Much of that CO2 increase is attributable to the 6-fold increase in human use of hydrocarbon energy. Figures 2, 3, 11, 12, and 13 show, however, that human use of hydrocarbons has not caused the observed increases in temperature." (ttp://}

Rising Sea Levels

All animals will be greatly affected by climate change and global warming, Even the birds who depend on nectar for life

Many island nations are already feeling the effects of oceans rising in volume, even Japan is now sinking on the east coast following its latest earthquake. High tides are inundating farm land and swallowing homes in many locations globally and melting ice is causing increased global warming,

Animals are facing extinction, such as the polar bear, because of ice melt while other animals are unable to breed properly because of increased temperature. It has also had an effect on the bees who are fighting changing patterns of flowering among plants, now coming out earlier and dying off before the bees have built up their numbers enough to harvest the nectar,

Other insects are thriving which are dangerous to normal food productions, such as locusts whose arrival can devastate crops before they can be harvested,

Agriculture is also struggling against desertification and salt rise on once fertile land, It's not looking good for the future of human life.

      I did pretty well, thank you for reinforcing us taking care of the air that we need to breathe, hadn't thought of it as taking our breath away, well said and done!

      London did have major air pollution problems - and on some of the very busy roads it is still pretty bad, but we have increasingly tight emissions control. The air quality here is definitely improving. With oxygen - beware - 100% pure oxygen would probably be toxic. All things in balance. The most suitable air for humans is that which we were adapted for, not super oxygenated, or over carbonated. I had no idea that oxygen is magnetic. The o2 experiments video is brilliant. It is a a shame that some of those videos didn't work any more.
