<div style="text-align: justify;">Agriculture
is responsible for approximately 30% of global warming, mainly through
carbon dioxide (CO2), methane (CH4) and nitrous oxide (NOx) emissions.
Numerous studies have shown that carbon dioxide emissions from organic
farming are 40-60% lower per hectare than conventional systems. This is
mainly because organic farmers do not use synthetic nitrogen
fertilizers. Research has found that the very nature of organic farming
not only makes it less of a contributor to greenhouse gas emissions but
it can also act as a valuable sink for carbon dioxide. If only 10,000
medium sized farms in the US converted to organic production, they
would store so much carbon in the soil that it would be equivalent to
taking 1,174,400 cars off the road, or reducing car miles driven by
14.62 billion miles.<br></div><i>Fonte di informazione:</i> «The Organic Advantage», n. 30, 17 novembre
