Animals have needs of their own. The needs of the animals may come into conflict with the demand for efficiency and productivity in livestock breeding and animal husbandry. Today we are aware that it is not in our interest to treat animals badly. All human activities that involve the use of animals must promote animal welfare. Treating animals well throughout their lives is an ethical issue.
Many animals live and die in man's interest.
Animals give us food and material for clothing. We keep pets just for our own fun. But animals are at the same time beings with needs and wishes that must be considered. But sometimes we are not as considerate towards animals as we should be. Animals are sometimes exploited.
