This colossal scientific work, which is very simple to read, is an excellent source of information on vegetarism. Astonishing, this book surprises and teaches us as much on alimentation than on the animals themselves. It gives us an holistic vision of things, and demonstrates the great value of vegetarism on all levels, whether it be nutrition, ecology, science or even, spirituality.

An extremely interesting book on all levels, that will surely answer many questions, and spread many solutions. :)
