An effective and novel introduction to the nature and ecology of coral reefs, Coral Reefs which has been both written and illustrated by Jason Chin, is both engaging and informative, presenting not only general and specific information and details about coral reef communities and their environs, but also demonstrating the unfortunate fact, the unfortunate truth that coral reefs are not only vibrant and diverse marine communities, but that many of these communities are increasingly being endangered by and through human encroachment, overfishing, pollution, climate change etc.
Now the entire concept of Coral Reefs, of a young girl going to the library to read a book about coral reefs and then having both herself and her surroundings (her local library, her local city) literally become part of a coral reef community is quite visually stunning (and some of the illustrations, some of the scenes feel almost reminiscent of a lost city under the sea, like Atlantis). However, first and foremost, Jason Chin's gloriously bright, descriptive pictures provide not only a successfully rendered mirror of and to the presented narrative, they also reiterate one of the main messages, one of the main points of Coral Reefs, namely that coral reef communities are in many ways like huge, underwater cities. And like our own cities, these coral reefs, while vibrant, diverse, and constantly on the move, are also vulnerable and can be threatened by both natural and man-made, artificial phenomena. And finally, regard to age suitability, the actual text of Coral Reefs is pretty dense, wordy and rather involved, and I would therefore tend to recommend this book more for older children above the age of six or even seven. For while I do in fact believe that even younger children would likely enjoy the brightly descriptive illustrations, the narrative flow is definitely a bit slow moving and detailed at times (and thus might be a bit distracting and difficult for the very young, not to mention that the featured threats encountered by coral reefs are or at least could be a bit hard for toddlers, for children up to the age of six or so to adequately fathom and comprehend).
