Some day ago I'm come to the end of the book "The diversity of life" di Edward O Wilson. A very interesting book about the life on the earth, biodiversity and conservation of the ecosystems. A book that speak of the very little knowledge of the humans about nature (vegetals and animals) and the way in which each of us would have to undertake to stop to the destruction of species. Humans are the cause of this new great extintion, comparable with the other great extinctions to the time of the beginning of life on the earth.
It's not always easy to read, but it's a book that maybe should be read from all the people, because an ecological sensibility is necessary in each person, expecially in this moment.
