This conclusion chapter presents some closing thoughts on the keyconcepts discussed in this book. The book offers a new way of thinking about food and ethics. It highlights some of the benefits of adopting the human diet. The first is that the human diet is our natural diet. Second, the human diet is the best solution to environmental issues. Third, the human diet would drastically reduce the use of energy resources based on fossil fuels, which are non-renewable, as well as other natural resources. Fourth, the notion of using animals for food and other purposes represents one of the world’s greatest injustices. Failing to treat animals and the environment with respect are certainly less than fully virtuous. Using animals for out benefits and consuming their bodies and their secretions and eggs exemplify a variety of vices, in particular, indifference to the value of nature, ignorance, self-importance, self-indulgence, unfairness, and intemperance.
