impossible to deny that a person is significantly (and not the best) impact on the environment, in particular on the carbon cycle in nature.We are able to maintain the ecological situation on the planet at least as habitable as possible in the long term.But why, in fact, so important to the presence of carbon?What it's going, how it affects us, and whether we can affect the circulation in the nature of this important element?
Virtually every form of life on our planet contains carbon.Hence, it is necessary for the normal existence of all species.Why are we afraid of the fact that the carbon content increases rapidly?Burning oil and gas in the operation of machines of enterprises emits huge amounts of carbon dioxide, breaking the carbon cycle in nature.Biosystem Earth ceases to cope with the quantity.
where there is carbon?
The seemingly negligible concentration (0.04%) carbon is present in the atmosphere as carbon dioxide CO2.But this is enough to support the livelihoods of the earth's vegetation.
carbon contained in the soil and sediment - in the terrestrial biosphere.
As already mentioned, this element is present in large quantities in the ocean in the form of living and nonliving marine organic matter and has dissolved.
Another store carbon - mineral resources, usually of organic origin.
Where does?
carbon cycle in nature, as well as any other substance, implies that it is taken from somewhere, then somewhere disappears and comes back.Let's see how this happens with carbon.
• In an atmosphere of carbon exhale animals and humans.•
dead organisms of plants and animals treated with bacteria that secrete involving oxygen while carbon dioxide or methane, wherein carbon is also present.
• Carbon dioxide is formed as the combustion of oil, coal, peat and natural gas.
• Forest fires - the same source of the gas entering the atmosphere.
• Another major source - the activity of the active volcanoes that emit a lot of carbon dioxide, steam and sulfur dioxide.
• Cement production as a result of human activity;using heating calcium carbonate (CaCO3), emit large amounts of carbon into the atmosphere.
• There is much talk about global warming.By heating the surface of the ocean further release carbon dioxide from the water.
Where to go?
If all the carbon released into the air and stayed there, we would have long since suffocated, and life on Earth would cease to exist.But the circulation of carbon in nature suggests that he is out of the atmosphere somewhere disappears.Where?
• Thank you for cleansing the air of carbon dioxide need to tell the trees that are the main repositories of the element.Moreover, the carbon can be stored in them for hundreds of years.Especially useful in this sense, the young trees that grow quickly and so quickly consume carbon.
• The lower the temperature, the more carbon dioxide it becomes soluble, and the cold surface of the water closer to the North Pole it perfectly absorbs.But global warming threatens the ocean begins to evaporate the carbon dioxide back into the atmosphere.This is another problem that worries scientists and all mankind.
• Another major factory for recycling of carbon - marine organisms that live in the upper layers of the ocean.They absorb carbon to build their cells.Rough calculations scientists say 36 thousands of gigatons of carbon in the oceans.
• otmiraya, sea creatures (their solid portion) are deposited on the seabed, over time, add up in sediments.
Large circulation of substances in nature - a well-established system in which interference could lead to unpredictable consequences.
