The easiest and most effective thing you can do to show your personal commitment to animals and the environment is to give up consuming animal products and byproducts. Going vegan directly saves dozens of animals every year (the average person in the U.S. eats 40 chickens a year). By going vegan, you are also helping to stop rainforest and top soil destruction (cattle grazing is a leading cause of this), water pollution (animal agriculture runoff is devastating local bodies of water), and the destruction of wildlife habitat.
If you are new to veganism, find a vegan friend or group. You can find vegan starter kits and other great resources at:
