Cow Appreciation Day is celebrated to remind us how integral cows are to our daily lives. In some regions, such as parts of India, cows have significant religious meaning. In some cultures, cows are considered as the oldest form of wealth. Cattle today are the basis of a multi-billion dollar industry worldwide.
