Acharya Prashant explains that over the last few centuries, there has been a clear progression in the declaration of rights, from the Rights of Man to the rights of slaves, and most recently, the rights of women. He predicts that the current century, catalyzed by the threat of climate change, will see a clear declaration of a new relationship between man and the environment. This will manifest as an acceptance of the right of animals to live and the right of all species to survive in their own way, whether agreeable to man or not. This change, he asserts, is inevitable and necessary for both mankind's dignity and its very survival. This shift will happen in two ways: some will live harmoniously out of understanding and love, while others will be compelled by their own self-interest because their survival will be threatened otherwise. Mankind cannot survive if it does not know how to relate to the world outside its own body. He connects this to mankind becoming more readily accepting of its animal nature, which is not as suppressed as it used to be. He points to the beard as an indicator of this animal nature, stating that being comfortable with one's hair signifies being comfortable with the soil, the jungle, and the animals. If one is not comfortable with the jungle, one can never be comfortable with oneself. He explains that when one looks inside, one finds all of nature, making it difficult to consume animals, which would be like consuming one's own liver. Finally, he notes that the hope for external solutions from science and technology to solve man's internal discomfort has been shattered. Since all outward directions have been exhausted, man will necessarily have to look inside.
