Query: Interesting ideas but too loosely written

While I found his concepts very interesting and many of his stories beautiful in and of thesmelves, Nabhan fails to bring his book into a cohesive argument. He vaguely alludes to his concepts of the importance of biodiversity to cultures, and how a diversity of cultures promotes biodiversity, I felt as if I were drowning in nostalgia as he told this and that tale without making their significance clear and... significant.There were interesting thoughts and stories, but as an entire book, it disappointed me.
