sooo...

1) China dumps their sewage on veggies, and thus potentially has less sewage disposal problems...

2) The US has put sewage on fields and it made all kinds of people sick

So are we just doing it wrong? Or is it because if sewage on your veggies makes you sick in China, you can't sue anyone? Maybe Chinese people have magical poo? What is the deal here?

I re-read the chapter that dealt with China and their use of waste in agriculture, and I didn't see an answer to this. Ms. George says in the book that the Chinese have been using human waste as fertilizer for 4,000 years. Maybe historically (pre-industry) this waste was mostly organic, while the 'Class B biosolids' suspecting of sickening people is modern-day sludge that contains metals and other industrial waste? It’s a great question, and just for the hell of it, I e-mailed it to the author. She blogs on these topics pretty regularly; maybe she’ll touch on this one.
