ISBN 0870446401 - As usual, National Geographic's photography is the highlight of their book, making the text of secondary interest. The text is simple, easy to read and to the point.
Animals are affected by people and sometimes require help to survive. Alligators killed nearly to the point of extinction, terns that need a secluded beach free of people and many other animals fill the pages. The photos are fantastic and the last page includes wonderful information to help your child learn more on the topic.
My only gripe is the photo of a "Warning, Proceed with Caution" sign for the protection of manatees includes an obviously speeding boat! Still, even 20 years after being published, the information inside is not outdated at all (which is a bit sad from the animal point of view!). Teaching our kids to value animals can't have a bad side.
