Here's a good article from Channelnewsasia.com about the economic impact of H5N1 in China.
Although the value of poultry production amounts to only about two percent of annual GDP, the industry employs some 14 million farmers and workers.
The government has agreed to give farmers 10 yuan (1.23 dollars) for each grown bird culled and half that amount for chicks and ducklings. But 10 yuan is just half the cost of raising a chicken and does not cover the lost earnings from selling eggs.
Fourteen million people in China make a living from poultry...a small percentage of China's population, but equivalent to almost half of Canada. Add them to the tens of millions already looking for work in the People's Republic, and the mandate of heaven may be running out for Beijing. If H5N1 doesn't scare you, then the thought of China spiralling into anarchy certainly ought to.
