When you burn fossil fuels to make enrgy, carbon dioxide is released. So, if you burn less fossil fuels, less carbon dioxide is released.
The amount of carbon dioxide a person produces
carbon dioxide :p
Respiration :)
Solid carbon dioxide is not dangerous but avoid contact with skin and eyes.
It's in the air and we exhale carbon dioxide.A small percentage of the atmosphere is carbon dioxide. Carbon dioxide is released by the metabolic processes of organisms, and by our burning of fuels. In recent decades, the amount of carbon dioxide has increased so much, some scientists believe maintaining the current amount of carbon dioxide will devastate Earth's climate. Actually, today there were festivals held all over the world to make people aware of this issue. See http://www.350.org/
30 billion tons
of course :) :)
By expiration carbon dioxide is released.
Forest fires increase the amount of carbon dioxide in the atmosphere
Carbon Dioxide because without water you die and with carbon dioxide(concentrated in large amounts) you will have trouble breathing, or possibly die.
In pre-industrial times, the amount of carbon dioxide (CO2)that animals breathe out was matched by the amount absorbed by plants, so that the concentration of atmospheric carbon dioxide remained remarkably stable in the range of 260 to 280 parts per million (ppm) over a very long period. Adding additional carbon dioxide by burning fossil fuels, overwhelms the carbon cycle and causes the atmospheric concentration of carbon dioxide to rise beyond this range. Deforestation can break the carbon cycle, first by removing a store of carbon which will be released as additional carbon dioxide into the atmosphere, and in some cases by reducing the ability of nature to absorb carbon dioxide from the air.
