A few figures bear witness to this. In 60 years, 300 new infectious diseases have appeared in humans, such as AIDS. In the same period, the incidence of allergic diseases such as asthma or autoimmune diseases such as type 1 diabetes has almost doubled or even tripled. As for the list of various pollutants, it continues to grow, and with them a host of diseases that may be linked to them.
In this book, the author shows, with supporting examples, the impact of Man on his own health. He gives a special place to the bacteria in our intestines, which are essential to our survival and whose ecology is also disrupted by our lifestyles. How can we understand the emergence of new diseases and how can we prevent them? Can the human species adapt to the changes it has itself caused? These and many other questions are answered by the author. In this book, he draws a nascent discipline, that of an ecological approach to health taken as a whole.
