PROBLEM: Needed more suspense. . After Box's first three excellent books, I found this a bit lacking.  It felt very slow at times and had a number of things left unexplained.  I don't mind the element of mysticism but it didn't feel complete.  Joe, his family and friends are great characters, the story definitely had me turning the pages and completing it in a day but it wasn't quite as strong as his previous books.    Don't misunderstand; this is still a very good read and a series I shall continue to follow, but I hope the next entry will have a bit more suspense to it.

SOLUTION: POS

PROBLEM: What we know about constraints on population growth . Obviously, the population of the world has been growing dramatically for the past few centuries.  How high can it go?  At how high a level can it be maintained?   What restrictions are placed by the available resources, such as food and water?      This book asks many of the right questions.  And it admits that we don't have all the answers.  But it does give some clues about where we may be headed.    Cohen shows that basically, if we want to support people indefinitely on 3500 kilocalories per day from wheat energy, with 9000 cubic kilometers of annual fresh water supply, well, we can support only 5 billion people.  We're already beyond that.  Right now, we're using up resources at an incredible rate.  And while the Earth could support 10 billion people in theory, it is hard to see how it could do that for long in practice.    The author thinks that we'll never get to the absolute maximum that the Earth can support.  Most people would all be right on the edge of starvation, and we'd simply be unable and unwilling to stay in that state indefinitely.  But I did realize after reading this book that we could stay at about 5 billion people for a very long time if we put our minds to it.  Standards of living would not be high, but they would be tolerable for the majority, and the ones who found such a life acceptable would keep having children who found it acceptable.    Those of us who have political views ought to wonder if time is on our side or not.  And that is why I think it makes sense to try to imagine what options are available for our mutual future.  That's why I think this book is worth reading

SOLUTION: POS

PROBLEM: Thank God It's Over! . The only reason I finished this book was it was a book club pick - I read a lot and it takes a really bad book for me to quit. This book is just never ending - no plot and a useless read. I can't believe so many people are giving it a good review. The constant narrative sounded like a neat way to write but it turned out very exhausting to read. Don't bother

SOLUTION:
NEG
