Bill McKibben wrote the first account for a popular audience of the science of climate change. And, while I haven't read it, if it's anything like this collection, he did so with clarity and concision enough to make it accessible to most. That seems to be the most impressive part of his writing. I don't think I really liked these essays for their poetry, but for their commitment to getting across the basic truths of Bill McKibben's life and a few basic truths concerning the state of the planet's life.
This volume holds essays about the joys of, threats to, and end of nature. McKibben writes passionately of wolves, protest, and global warming. He pens eloquent odes to Edward Abbey and Wendell Berry and a painful remembrance of his father in his dying days. Very rarely did I feel I wasn't getting what he was getting at.
Ultimately, I liked this book because, through it, I grew to like Bill McKibben. A lot of the science he discusses needs to be updated, a lot of his stories might be out of date, but his passion and care for the world comes through clearly and powerfully. Granted, this is a highly curated selection, but if it is at all representative, it reveals a writer who cares in a way I would like to care. It reveals a writer who has climbed to near the top of my list of writers with whom I'd like to grab a coffee. He's at the top of the list for hiking.
