Vegetarians eating meat?

I just read in an article from the book Best Food Writing that vegetarians are starting to convert back to eating meat. However this meat is from sustainable small farms that produce grass fed or free roaming livestock.

All the power to them we are built to be omnivores not to just eat veggies or just meat as much as we might want to. I think it is important to have niche agriculture that can produce for these different branches of demand. Although this type will probably never be able to support the worlds population it gives vegetarians a way to sneak meat.

A question if you are a vegetarian why are you one what made you make the big step?

And if so aren't you as unhealthy as the cattle that you say are living unnaturally?
