"Total GHG emissions from livestock supply
chains are estimated at 7.1 gigatonnes CO2
-eq per
annum for the 2005 reference period. They repre-
sent 14.5 percent of all human-induced emissions
using the most recent IPCC estimates for total an-
thropogenic emissions (49 gigatonnes CO 2
-eq for
the year 2004; IPCC, 2007)"
Surprisingly there are fewer cows than people, but there's still a billion cows, and a billion of anything adds up quickly.
That's not to say that the other things aren't important as well. Gas flaring from refineries is a pure waste that should be drastically curtailed.
