Some comments may Yegor Gran fun, and maybe even be used in one of his next books ... Indeed, I think the book is not written to be taken seriously and does not purport to address scientifically the subject of ecology. The author has fun and amuses us with our contradictions, our (pseudo?) Convictions, and belies humorous, bad faith and crispy examples, the arguments that are served daily eco us to justify our actions or we feel guilty when we skeptics. This book is a great breath of fresh air, fun candid moments are numerous and the curiosity of the author treats us. We want more.
