informative reflective fast-paced

generally enjoyable and fun read! great summary of earth's geological history and a bit of life on earth. loses its sharpness when beginning to discuss hominids' evolution. fails to stick the landing at the end during his call to action against climate change, but it was an important point regardless. 

due to the book not being about global warming and the anthropocene, he takes on too much at the end by trying to make an optimistic but urgent call for changing how we handle the environment. i get why he did it and it was as good as it could have been for the length, it just didn't feel as solid as the rest of the book.
