Do We Need Pandas written by Ken Thompson and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2010 with Biodiversity categories.

"How much do we really know about the species that make up the natural world? In this fascinating book Ken Thompson explains what we do and don't understand about biodiversity. We know that most species remain undiscovered, and that biodiversity is gravely threatened--by overfishing, habitat loss, pollution and climate change. Life on Earth has previously experienced five episodes of mass extinction, and we are now in the middle of a sixth. Do We Need Pandas? surveys the Earth's biodiversity, its origins and some of the threats it currently faces. It then asks how biodiversity loss will affect the human race. Will we even notice, and if we do, what will we notice? It asks what we should be doing to secure the survival not only of the species with which we share the planet, but of ourselves--and whether we need to be more concerned about ecosystems as a whole than about iconic species."--Page 4 of cover.

How much do we really know about the species that make up the natural world? All over the world, biodiversity is gravely threatened – by overfishing, habitat destruction, pollution and climate change. Yet life on Earth has previously experienced five episodes of mass extinction, and nature has repeatedly proved itself to be a resilient, regenerative force. In this fascinating book, ecologist Dr. Ken Thompson surveys the Earth's biodiversity, its origins and some of the threats it currently faces. Thought-provoking and deeply engaging, Do We Need Pandas? offers a non-technical overview of our ecosystems and expands on the causes and consequences of biodiversity loss. Importantly, it also examines what we should be doing to secure the survival not only of the species with which we share the planet, but of ourselves – and whether we need to be more concerned about ecosystems as a whole than about iconic species such as the orangutan and giant Panda.

Other recipes will dive deep into a particular dataset, uncovering new and unexpected insights along the way. The pandas library is massive, and it's common for frequent users to be unaware of many of its more impressive features. The official pandas documentation, while thorough, does not contain many useful examples of how to piece together multiple commands like one would do during an actual analysis. This book guides you, as if you were looking over the shoulder of an expert, through practical situations that you are highly likely to encounter. Many advanced recipes combine several different features across the pandas library to generate results. Style and approach The author relies on his vast experience teaching pandas in a professional setting to deliver very detailed explanations for each line of code in all of the recipes.
