The second half of the 20th century saw a new approach to the problem of human-animal relationships. If before animal welfare advocates did not put the question of whether they have a moral duty to the animals, the new animal rights movement that emerged in the late 1960s - early 1970s declared that the animals have the same rights as any other creature on earth - for life and freedom from suffering. Supporters of animal rights groups claim that when a person tries to be stronger to animals is the evidence of the same discrimination as the oppression of the people of the opposite sex or of a different race.
In his famous book Animal Liberation Peter Singer leads a conversation with two fans of animals to show the difference between an amateur attitude towards animals and their protection in the old sense of the word, and the struggle for animal rights.
By determining the position of the supporters of Animal Rights, another famous American participant in this movement Ph.D. Tom Regan in his book Fight for Animal Rights and The Case of Animal Rights calls such purposes: the rejection of all kinds of animal abuse associated with the infliction of suffering on animals or killing, their use for food, for fur and skin, the use of animals in the experiment and in entertainment.
The beginning of the animal rights movement can be regarded with the publication of a great article Animal Rights by writer Bridget Brophy. In the article, Brophy said that the relationship between Homo sapiens and other animals is a ruthless exploitation. She said that people use animal’s work, eat them and dress in them, using them to serve their prejudice: If before people had to sacrifice them to gods and pull their insides to predict future, now people sacrifice them to science and experiment on them.
The animal rights movement was initiated and spearheaded by highly educated people, doctors of philosophy, psychology, so to speak, the elite of the English and American intellectuals. This marks one of the active participants in the movement, Richard Ryder, in his book Animal Revolution. He pointed out that the liberation of animals is perhaps the only one of its kind movement among other movements for liberation from the standpoint that it leads and inspires the unusually large number of professional philosophers; rarely any problem was so rationally reasoned and intelligently defended.
The recognition of animal rights raises the question of right and wrong actions without regard to their effects. The right doesn’t depend on the good. Morally right actions cannot be assessed from the point of use. Improper action is always morally wrong, although it may benefit someone.
