For the science buff and particularly for those still studying biology, this book is a provocative investigation into the vital part that water plays in our existence and how it must be extended as a resource if life is to survive on this planet. The pollution abuses of fresh water, the manufacture of rain through cloud seeding and the de-salinization of sea water provide excellent information for both conversation and debate. The prospects for the future in terms of research in water conservation reads with all the verve of good science fiction.
