Le foreste difendono il pianeta dai gas serra: ma l uomo deve aiutarle

In the global carbon cycle there is more and more evidence of the importance of forests. In fact, if they represent about 30% of emerged lands, the carbon contained in these ecosystems makes up for 80% of the aboveground carbon and 40% of the belowground carbon. Forests are responsible for 60-70% of the main productivity of all the ecosystems on the earth and, in these last 30 years they have absorbed 20 to 30% of greenhouse gas emissions caused by human activities. This confirms the importance of their role in the global biogeochemical carbon cycle especially with reference to carbon emission increase in the atmosphere and to climate changes currently under way.
