It took me a deceptively long time to finish this book. In reality, I finished it in three or four sittings, but I put it down for a very long time before the last sitting—it's not the type of book you can read at any time or in any physical/mental state. It is very engaging, but extremely heavy (though not without humour).
I appreciated the very broad spectrum approach, and the provision of information and history that many people already 'in the field' might consider common knowledge and not worth explaining. The author is also very honest, including acknowledging his own hypocrisies and struggles etc., which is much more relatable than hearing a sermon from an eco-saint.
It's a book that captures the passion, confusion, hopes, outrage, tiredness, tirelessness, anxiety, optimism, and listless apathy that seem to be simultaneously inherent in a mind trying to live in this age of the world.
Unlike many sources of information, which leave one feeling utterly helpless, or angry, or depressed, or delusionally hopeful, I come away from the book feeling like I had a good, deep, important conversation with someone. It doesn't solve the dilemma, but it certainly allows one to begin to face it.
