This idea that animals have to suffer horribly in order for people to eat meat is not really true. Take a look at a story about
Temple Grandin and her innovations in slaughterhouses. She has also made huge changes in how animal handling facilities are built.
And even though the poster Josh feels that a lot of people do not raise and butcher their own meat (or hunt it), if people would consider that this is a big world and does not just consist of the United States they would see that this also is not true. For example if you go the highlands of the Andes, these people raise and butcher their own meat. There are a lot of people right here in the US that raise and butcher their own meat. In fact nearly everyone I know in my county does this.
A lot of this protein is raised on very sparse vegetation. People can not eat grass. They can not eat brush. However animals like goats and llamas can. In some parts of the world this is the only way to survive - to allow your lambs to turn scrub into lambchops.
My farm is not suitable for growing typical food crops. The elevation is a little too high, there is not enough precipitation and the ground is pretty rough. I can grow some dandy native grasses and forbs, though, so it just makes sense to me to turn that into hay or pasturage for cows, goats, sheep etc. since I can't eat it.
I am very happy for people who want to be vegetarian. I have no issue with that. I
DO have an issue with PETA, who seem to me to be so completely uneducated about animals it just amazes me. And even this would not bother me, if those same people were not trying to dictate to me how I should live.
