Some relevant articles from
Peter Singer's home page
Factory Farming - A Moral Issue.
Animal Rights - The Right To Protest (another subject very dear to my heart).
There should be no Room for Cruelty to Livestock.
These articles look really interesting. Guess what I'll be doing in work today!
(there are other related articles etc on his site, and many on other subjects that look equally interesting).
If anyone has read this far and
still cares, he appears to be a part of this overall webthing:
