The main reason I do not purchase, use, or consume products with animal-derived ingredients is that buying these products sends a tacit message to their manufacturers that as a consumer, I do not care if their products contain ingredients derived from slaughtered animals. If most people do not care, then companies have no incentive to change their practices. If it becomes economically advantageous for them to switch to completely vegan ingredients, then they will do so. To avoid products with animal ingredients, I read all labels carefully and I have learned to recognize common animal products in products ranging from soap to many processed foods. Searching for vegan products is really quite easy. It just takes a little time, energy and the knowledge that the goal you are working towards is worthwhile and just-. a more peaceful, compassionate world for all living creatures.
