Three stars may seem a little harsh, but remember that three stars means I like it.
And there is a lot to like here:
* a very consistent design scheme that communicates quite well
* a well-developed illustrative style that is clear and consistent, but also rich with personality
* a great introductory section that introduces a lot of key terms and conventions. This is one place where the book most fulfills it's promise
* great concluding sections, turning from ecosystems to broader cycles, human impacts, and next steps
* a lot of thought, heart, and work clearly went into this book
* it made some choices that really got my attention; I don't know if they are right, but they made me think.
The major choice that got me thinking was the pervasive glass jar motif. It suggests a number of aspects, some of which I agree with, some of which I disagree with, some I don't know how I feel about, and mixtures of these. This glass jar motif suggests that different ecosystems:
* are cleanly delimited
* are fragile
* are preserved in a single unchanging condition when treated well
* are isolated from outside environmental influences
* are treasures
* are here for human observation and judgment
* etc.
It's interesting how much apparent meaning such a choice communicates, and one wonders how much was intended. Even beyond this meaning there is all that this choice says stylistically; a touch twee but still elegant.
I also found it really interesting that the book was in the science section for adults. There is really nothing, perhaps other than its length, that dictated that it should be for adults. In fact, I ended up buying it so I might give it to some younger relatives after I had read it.
What prevents me from really liking this book was that I didn't feel it delivered on the promised of the title of the book, to elucidate the "wondrous workings" of planet Earth. Instead of delivering on the promise of workings or mechanism, what is on offer are settings. Much of the book concerns itself with describing another setting, where organisms have immutable interrelationships between each other instead of developing into and out of niches through evolution. As a result, the middle mass of the book is almost over-consistent, repetitious in its structure, and is much less interesting than its endpoints as a result.
Overall, while this book was not a detailed visual overview into the workings of how ecosystems develop and change, it still was informative but also suggestive.
