Okay, I am somewhat of an environmentalist, and the caricature bothered me too-although truthfully, I know it's possible that some people can be that extreme. However they are usually Amish.
Anyway I tried to read it to my DS9 to try and get him interested in reading again (he seemed to have lost interest) but he just couldn't get into it.
Also I didn't see a lot of advanced astronomy info in the book that we hadn't covered in other material (although I do love the idea that they wrote this book). Still the interest wasn't there so the book went back to the library.
