This book on biodiversity encompasses concepts and research findings on this topic. The CBD or Convention on Biological Diversity defines biological diversity as "the variability among living organisms from all sources including, inter alia, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part: this includes diversity within species, between species, and of ecosystems." This book comes at a time when the threats to biodiversity are enormous given the extensive destruction of nature under the name of "development." In addition to statistics, interesting organisms and facts with research findings, this book also briefly covers the threats and solutions to mitigate the threats.
