This idea was initially proposed by Peter Singer in his very famous book and my textbook- "Animal Liberation". The basic idea revolves around the key concept of "specism", just like racism, sexism, etc, specism means to have a preference for one species over another. In our case, we prefer our own species the most. This is a question of Applied Ethics in Philosophy, and as always, rather than giving a direct answer to the question, Philosophy gives multiple approaches to solve this problem.
