Global warming

Of carbon dioxide produced from the combustion of any organic material in the air, adverse effects, but we do not feel in the case because the carbon dioxide from natural ingredients to the air
It has been observed in recent years that the rate of the gas in the Earth's atmosphere has risen slightly from rate measured at the beginning of this century, and the reason for this increase in the proportion of carbon dioxide to the massive amounts of fuel you burn industrial plants, gas stations and combustion engines internal transport and communications
It is known that the combustion of one gram of organic matter gives the 1.5-3 grams of carbon dioxide, and if we imagine that there are several billions of tonnes of fuel burned in the air each year, we may be added to the air each year about 20 billion tons of carbon dioxide , which represents 0.7% of the amount of this natural gas in the air
