Biodiversity: Explore the Diversity of Life on Earth with Science Activities for Kids introduces middle schoolers to the evolution of life on Earth, beginning with the first single-celled organisms that emerged 3.8 billion years ago to the complex, multi-celled organisms that exist today and make up the tree of life. Biodiversity is found everywhere on the planet--on land, in the water, and even in extreme environments such as ice and volcanoes. Biodiversity can also be discovered by looking through a microscope at tiny worlds of organisms that can't be seen with the human eye. There are whole microbiomes beneath our feet, in puddles, and even in our belly buttons! All of this biodiversity on Earth helps keep the planet in balance. Biodiversity is also important to humans because it provides food, shelter, clothing, medicines, and more. However, the rates of biodiversity loss are increasing because of human activities. Climate change, pollution, habitat destruction, over-exploitation--these are all critical threats to biodiversity. There are, however, ways to slow or stop this loss through conservation and sustainable development. Biodiversity includes hands-on STEM activities and critical thinking exercises to encourage readers to consider the threat to biodiversity and figure out ways to be part of the solution. Activities and projects include making biogas, a microscope, a tabletop biosphere as well as planting a bee garden, studying a soil sample and water sample. Fun facts, links to online primary sources and other supplemental material, and essential questions take readers on an exploration of the incredible biodiversity on Earth.--

La quatrième de couverture indique : "Comprendre la biodiversité La biodiversité est aujourd'hui l'un des maîtres-mots de tout discours environnemental. Après une trentaine d'années de diffusion du terme, un examen attentif fait pourtant apparaître que son succès médiatique s'est accompagné d'un affaiblissement de sa validité scientifique. Ont surgi nombre d'arguments qui s'éloignent des faits avérés ou des analyses sérieuses, conduisant ainsi à un catastrophisme ambiant mal fondé. Alain Pavé, dont la compétence scientifique dans le domaine est incontestée, propose une analyse critique novatrice et bienvenue, riche d'exemples concrets souvent surprenants, de l'escargot de Quimper à l'ours pas toujours blanc. Loin de prendre le simple contre-pied des idées reçues et d'ouvrir la voie à un quelconque écoscepticisme, l'auteur montre que la prise en compte des réelles menaces qui pèsent sur le vivant demande une compréhension beaucoup plus fine de sa diversité et des mécanismes, évolutifs en particulier, qui la gouvernent et où l'aléatoire joue un rôle déterminant. Il s'agit ici rien moins que de proposer une refondation du concept de biodiversité, à la mesure de son importance et de l'intérêt qu'on doit y porter. La pensée écologique ne pourra que profiter de ce changement de perspective."

Biodiversity and Protected Areas assembles twelve topics from around the world, illustrating the complexities and promise of addressing the biodiversity crisis. Authors from Mongolia, Africa, India, Canada, Iraq, and the United States dwell on particular aspects and challenges relevant to those regions. Lessons and approaches from interesting localities, coupled with global analyses give the reader a synthetic view of emerging problems. The opportunities for understanding common issues across different geographies abound, such as comparing local conservation in sub-Saharan Africa with a distribution of very small protected areas in Massachusetts. Several topics will be of immediate interest to policymakers. The book is illustrated with numerous color maps and figures and the authors strove for clear, uncomplicated writing. The editors provide an overview of chapters, placing them in the context of other biodiversity and protected area literature. Students and conservationists attempting to broaden their views of biodiversity and protected areas should find this collection to be interesting.
