Why is carbon dioxide dangerous in the air?

Your blood works by exchanging carbon dioxide and oxygen with the environment.Oxygen comes in because there is less of it in the body (from use) but more of it outside (from plants)Carbon dioxide leaves the body because there is more of it inside (from use) and less of it in the air (from plants)If there is too much CO2 in the air, it would never leave our body and we would die. Carbon monoxide (CO) is even more dangerous.CO2 also acts like a blanket and traps heat causing the earth to warm up.
Who told you that carbon dioxide in the air is dangerous ? Do you realize that all trees and other plant life need carbon dioxide to survive? Photosynthesis takes carbon dioxide and water into the plants which synthesize( bring together) certain carbohydrates and release oxygen into the air.
Carbon has one of two options: it has either to be suspended in gaseous states and become part of the volume of air, or it can resolve to its native form, which is atomically of solidity. Therefore, it can resolve to air or repair to its steady-state -- in matter, such as in life forms and plants, the waters, in soils, particularly in rock or in seabeds and the floors of the great oceans.
Where Carbon overly abounds, an imbalance ensues -- which is the case with anything -- which yields an indication in some form. In this case, Carbon absorbs and retains and reflects or expresses heat energy -- since again, the carbon atom is not a gas but a solid but does have an affinity with oxygen, which exists diatomically; that is, it naturally exists as a molecule of two atoms, which is why CO2 is the result: it takes 2 atoms of carbon ions to balance of the natural configuration of oxygen's 2 ions, though carbon atoms are more massive than oxygen atoms; hence, it has greater capacity to take in and store energy.
And so things heat up quickly when Carbon is partying with Oxygen...
Political leaders gathered in Kyoto, Japan, in December 1997 to consider a world treaty restricting human production of "greenhouse gases," chiefly carbon dioxide (CO2). They feared that CO2 would result in "human-caused global warming" – hypothetical severe increases in Earth's temperatures, with disastrous environmental consequences. During the past 10 years, many political efforts have been made to force worldwide agreement to the Kyoto ತ್ರೆಅಟಿ.
When we reviewed this subject in 1998 (1,2), existing satellite records were short and were centered on a period of changing intermediate temperature trends. Additional experimental data have now been obtained, so better answers to the questions raised by the hypothesis of "human-caused global warming" are now available.
The average temperature of the Earth has varied within a range of about 3°C during the past 3,000 years. It is currently increasing as the Earth recovers from a period that is known as the Little Ice Age,George Washington and his army were at Valley Forge during the coldest era in 1,500 years, but even then the temperature was only about 1° Centigrade below the 3,000-year average.
The most recent part of this warming period is reflected by shortening of world glaciers,Glaciers regularly lengthen and shorten in delayed correlation with cooling and warming trends. Shortening lags temperature by about 20 years, so the current warming trend began in about 1800.
Too much carbon dioxide is that the heat that is radiated from the sun what is usually released back into space is trapped in earth

The Dangers of Global Warming

Many natural cycles we depend on for our health and livelihood are changing. The experiences of these people and businesses give a preview of life in a warmer world. Also see common myths and facts about global warming's dangers.

More heat can cause serious health problems.
Diseases Spread as Climate Changes
One day in the spring of 1993, an otherwise healthy young man was rushed to a hospital in New Mexico because he was having trouble breathing. Within hours, he died of acute respiratory failure. He had been on his way to the funeral of his fiancée who had died from similar causes days earlier. Within a week, medical experts discovered a handful of similar deaths in the Southwest. All of the victims had been young and relatively fit.
The culprit? Hantavirus. Virtually unknown in the United States before 1993, by February 2006, 416 cases of hantavirus had been found in a number of states as far-flung as Florida and New York.
Hantavirus is a lung disease that is spread by carriers like deer mice. People contract the disease by breathing in the virus that has gotten into the air through rodent droppings and urine.
Scientists suspect a link between climate change and the 1993-94 hantavirus outbreak. Six years of drought followed by heavy spring rains in 1993 produced a burst of plant growth. This in turn led to a tenfold increase in the population of deer mice. Extreme weather, such as drought and torrential downpours, will be increasingly common as the Earth heats up.
