Ritical book review of Ernest Callenbachs Ecotopia.

I do not need any source. Please do not add any source. Just need 4 pages of book review.
This is what the book review must have below.

What does this book have to tell us about the environment? About environmental history? How does it fit into todays society? Consider Included in this review should be a discussion of why this book is part of an environmental history course and who should be reading it.
