I'd like to see more humane treatement of animals in farming, I'm sure their meat would even be tastier, and maybe when I'm rich and famous I'll look into buying meat certfied to be from humane, free range farming... but can't afford that on a graduate student wage... and I need protein for my brain to keep working.
With that said, I've been trying to eat more fruits and vegetables, as well as more fish, but I'm still used to thinking of veggies as side dishes, not a main course (and I have never seriously considering becoming a vegetarian).
I should also say that I find the radical attitude of many animal activists distasteful and misinformed. For me this is an issue for rational discussion not of the sentiment to which they so promptly appeal.
One thing which makes animal protein necessary is that most grains and vegetables have been bred for maximum size and growth rate, but not for high protein content... I don't see any animal activists campaigning for breeding plants with higher protein content. That still leaves the need for some essential aminoacids that only animal protein has in sufficient quantities... could be solved with genetic engineering, but most animal activists would oppose that too.
Which leaves us with one scientific answer to eliminating the need for animal farming: tissue engineering. Grow fillet in a vat by understanding and controlling tissue differentiation from stem cells. Now that would be great!

In the meantime, as much as I'd like not to, I have to keep buying cheap factory-farm produced meats.
