The greenhouse effect

The man, by the progress of the industrial civilization, has "discharged" into the atmosphere ever growing quantities of carbon dioxide. It is above all produced by industries, motors and heating systems. To support the growth of the towns and the development of the agriculture millions of hectares of forests have been cut down, in this way the consumption of the carbon dioxide in the atmosphere on behalf of the vegetables has been reduced a lot. The scientists think that an increasing of the carbon dioxide in the atmosphere could bring on a sensible increase of the earth temperature with consequent climate disorders.backavanti
