There are two forms of criticism of the concept of animal welfare, coming from diametrically opposite positions. One view, dating back centuries, asserts that animals are not consciously aware and hence are unable to experience poor welfare. The other view is based on the animal rights position that animals should not be regarded as property and any use of animals by humans is unacceptable. Some authorities thus treat animal welfare and animal rights as two opposing positions.[2] Accordingly, some animal right proponents argue that the perception of better animal welfare facilitates continued and increased exploitation of animals.[4][5] Others see the increasing concern for animal welfare as incremental steps towards animal rights.
