Conservation biology is an essential element for sustaining the biodiversity of this planet. Conservation biology is also known as "crisis discipline." In today's scenario, the world is undergoing some rapid transformation, and science instructs us about research, management practices, technologies and policies that can help protect the environment's naturally-occurring biological diversity. Certain chapters of this book present well-researched analysis dealing with guarded regions (Middle East), safeguarding biochemical and genetic diversity of carob tree, wild pear, shaping the health status of Amazon manatee, disturbing sex-ratios to benefit the natural world, and minimizing the gap between region and protection. This book approaches various threats to biological diversity from different point of views. The author offers room for reflection on the meaning and value of the word 'natural' on a planet now, tremendously, dominated by people.
