Animals are incapable of expressing their fear and pain in words, and cannot escape from cages and chains. As a result, we treat animals in ways we would never treat even the most evil animals in the world. We live in an interdependent web of relationships with all species. So, each of us is obliged to become aware of the amount of suffering humankind forces on animals and find ways to do less harm ourselves.
