The same installations that emitted 1.9 billion tons of CO2 in 2008 emitted 1.7 billion tons in 2009, according to Mr. Fages.
Deforestation is releasing globally about 1.6 billion tons of carbon a year.
In 2012 this planet will produce a record grain yield of 2.4 billion tons.
Furthermore, humans produce an enormous 7 billion tons of carbon dioxide per year.
Those crops are expected to boost global cereal production modestly, to 2.31 billion tons.
