Two facts about biomass  AARON COHEN  ·  JUL 02 2012

Fact 1: Of the 287 million tons that make up the global adult biomass, 18.5 million tons can be attributed to overweight or obese people. 32% of the world's excess biomass due to obesity is in the US, and the energy used to maintain that obesity could be used to feed 7.7 million people. Although the data used for this report is from 2005, it's still startling. (via @@jamie_bear)

Fact 2: "The total biomass of all the world's livestock is almost exactly twice that of humanity itself." (thanks, jon)
