Question

Why is there air? What purpose does it serve? I want to know what people think its there for. What if we aren't suppose to breath it?

Answer 1

Air is produced by trees,which is needed for life and all living things.

If there were no air- our planet would be desolate.

Answer 2

Air may mean:the mixture of gases present in the Earth's atmosphere . Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night.

The atmosphere has no abrupt cut-off. It slowly becomes thinner and fades away into space. There is no definite boundary between the atmosphere and outer space. Three-quarters of the atmosphere's mass is within 11 km of the planetary surface. In the United States, persons who travel above an altitude of 50.0 miles (80.5 km) are designated as astronauts. An altitude of 120 km (75 mi or 400,000 ft) marks the boundary where atmospheric effects become noticeable during re-entry. The Karman line, at 100 km (62 mi), is also frequently used as the boundary between atmosphere and space.

Answer 3

there is no purpose in anything that exists naturally. it's just there as a result of all the chemical reactions that occurred in the formation of earth and it produced an environment that happened to be suited for the development and growth of animals. if we aren't supposed to breath it, humans would not exists.

Answer 4

Not to mention it is a by-product of plants resperation.

What is oxygen?
Oxygen? We can’t live without it. Everyone knows that oxygen is one of the elements of air and that we simply die without it. We can survive weeks without food, days without water, but only minutes without oxygen. It supplies the energy or the fuel to maintain, grow, and repair every cell in our body. This clear, odorless gas is the most abundant element on the earth, and the most important element needed to sustain life.

How does the body get oxygen?
When air is breathed in, it moves into the lungs through a series of bronchial tubes until it enters microscopic air sacs called alveoli, where the oxygen in the air is able to diffuse into blood capillaries and there enter the circulatory system. Oxygen first travels to the heart. The veins there carry waste material in the form of carbon dioxide to the lungs to be exhaled. The arteries there carry the oxygen rich blood to the cells within the hemoglobin, an iron-containing protein with the red blood cell.


How does the body use oxygen?
When oxygen reacts with glucose, the end product of starch, fats, and sugars in the body, it produces carbon dioxide, water, and energy. This energy is stored in the body as ATP or adenosine triphosphate and can be regarded as the basic currency of the body. It is this currency that is spent for all the hundreds and thousands of reactions needed within each system of the body. About 90% of all the body’s energy is created by oxygen. It is needed to pump our hearts, digest our foods, build our immune systems, process information from our brain and nervous system, remove wastes – basically everything that is needed to keep us well. The more oxygen we have in our system, the more energy we produce, and the better we feel.

What happens when we deplete our bodies of oxygen?
Depletion of oxygen to the cells leads to disease and is probably the basis of all physiological disturbances in the body. In health, all the cells of our body are slightly alkaline. Oxygen is slightly alkaline, and when a cell is highly oxygenated, it is able to create energy (ATP), maintain its alkalinity, and sustain a healthy environment. When oxygen is reduced, it set ups conditions conducive to infectious organisms. Most pathogens – bacteria, viruses, fungi, parasites, and cancer cells -- thrive in an environment low in oxygen with an acidic PH. Pathogens produce their energy through the fermentation of glucose instead of oxygen. They simply cannot thrive in an oxygen rich, slightly alkaline environment. To reduce oxygen in the body is to increase the likelihood of disease.

Answer 5

We need air so that the pretty flowers can sway with the breezes.

Don't breathe the air.... it has germs.

Answer 6

We need air to stay alive... air is like soul to body...

Answer 7
