If you are a teacher of Yoga, this step should be old news, mastered. Period.
There are many ways to ensure that you are doing the most you can to end animal testing (these are just some of them):
Only buy products from companies that are certified and labeled as vegan and cruelty-free
Only donate to charities that do not conduct or pay others to conduct experiments on animals.
The internet is full of places to purchase cruelty free items! Buy in bulk and save.
Chickens enter the world on a metal shelf at a hatchery surrounded by thousands of other chicks. On their 1st day of life they are unable to see the sunlight or feel the earth beneath their tiny feet. They open their eyes and all they are able to see is darkness. On their second day of life baby chicks are shuttled along a conveyor belt of death where they are quickly sorted in a way that is completely devoid of any kind of emotion. Treated as commodities rather than living creatures, the female chicks are placed on one belt and the male chicks are placed on another, each leading to their own deaths – one, a relatively quick death, and the other, long and drawn out. All while chirping for their mothers.
There is no other species on the face of this planet that drinks milk past infancy from an animal of a different species than their own. Cows produce milk for the same reasons humans produce milk. Cows must give birth in order to produce milk. But in order to give birth a cow must first be pregnant, and in order for a cow to become pregnant, she must be impregnated by a device known as a rape rack.
The first time I witness the sound of the mother cow grieving for her babies (males are dumped in a trash pile and females are immediately removed so they don't drink "your milk") I literally fell to the ground and started grieving too.
