Anne-Marie,
Good points all....I don't take these numbers too literally, though I did spend a lot of time tracking down the estimates. For example, I was unable to get even an estimate of the amount of money that we spend on pest "control."

What I learned writing a trade book is that sometimes you have to sacrifice detail for the larger point (which you said you agree with in this post). This is even more true in blogs where I limit my posts to 1,100 words.

I am less concerned with whether we spend 10 versus 100 times the amount on killing animals than saving them than I am with the larger point that our relationships with animals reflects a moral schizophrenia on a massive scale.

I feel that I have at least partially succeeded if I can encourage intelligent and thoughtful readers such as yourself to think about these issues.

Thanks for taking the time to write.

Hal
