The best way to stop cruelty to animals is not to eat them.  Most of you probably can't imagine yourself giving up animal products entirely.  But once you give it a try, you'll see how easy it really is.  Commit to eating one meal a day without any animal products (including dairy and eggs).  Alternate between breakfast, lunch and dinner.

If you do this, you'll learn very quickly what vegans eat and why it's easy and healthy to eat a plant-based diet.
