1.6 Tons of Manure, I Doubt It

The Daily Green has an article mewling about how concentrated animal feeding operations or CAFOS - essentially gigantic corporate meat farms, can pollute more than a city the size of Houston Texas. They cite this figure:

A single farm, raising 140,000 head of cattle, can produce 1.6 tons of manure every year, more than is produced by Houston, Texas.

1.6 tons of manure every year? 1.6 tons is barely a single Harry Reid press conference! If you're going to engage in fear mongering, at least try to get the facts close to straight. My guess is they meant to say 1.6 million tons of manure or the entire DNC output in 2008.
