Seven Billion and Counting is intriguing  from the cover with the sub text of “the Crisis in Global Population Growth” to the final page with discussion of possibilities for a sustainable future.  The use of colorful photographs,  charts  and graphs show the hugeness of population numbers in the billions.  A grasp of this many humans on the planet is then discussed in the needs of these people as individuals.  For the planet to provide the basic, life sustaining  requirements, such as adequate food, water and shelter , decisions must be made beyond the boundaries of separate countries, regions or nationalities.  This book gives a clear, graphic presentation of viewing the planet as a whole organism to be nurtured and sustained in order to provide for a magnitude of human beings. Real solutions are recommended through education, public awareness, population control  and  sustainable farming.  This is a pressing problem that needs discussion and action on many different fronts.  Additional purchase for middle and high school libraries.
