Love it. Read it with a nod to my old self who once wanted to become a Molecular Biologist. This book should satisfy people with healthy curiosity about the earth. I do have to say that this book swayed me between feeling hopeless in face of nature and feeling like a world destroyer. To note, human have been in existance since a very short time and it's very possible the good old earth will continue to exist without us for another long time.An interesting trivia, I've just found out that my birth was accompanied by a welcoming bang from Mt. St. Helen.
