In “A Change of Heart About Animals”, Jeremy Rifkin states that animals have many similarities with humans; and people should change their old views about animals and treat them more respectfully. Rifkin proves this by giving scientific experiment results to show that animals can live like humans. The experiments focus on animal emotions, abilities to use tools or learn, and living habits.
Rifkin explains that animals can have similar emotions like humans. They have the abilities to change their emotions just like humans, and also determines by their positive or negative feelings. The example of pigs has well show that animals want to be together with others; otherwise they will feel depressed when isolated.
