I'm a vegetarian mostly because of inhumane treatment of animals, so the announcement that Burger King is going to only buy cage-free eggs, chicken and pork (after a phase-out time) is great news! You can see the NY Times article here. They apparently already have standards for how their beef is raised and slaughtered. They hope this will change the market for more humane treatment of animals, and that their competitors will have to change over, too.
As Friends I think we should care about the ethical treatment of all life, not just humans. I don't know that it's unethical to eat animlas at all, but they definitely should be treated with dignity in life and killed in a way that isn't traumatic.
