I finished Animal Liberation, by Peter Singer while on a plane to China. The book presents a compelling argument as to why we should not eat animals. Although it is not the primary reason I am eating more vegetarian, it certainly lends philosophical support. I have found it difficult to entirely give up meat, especially when we were on vacation in China. I suppose that the primary reason for this is that our society has evolved to use meat as a means of displaying wealth, since meat used to be relatively rare. As a result, large celebratory meals often have a fair amount of meat. Since we were in China for Chinese New Year, we had several such meals!
