In the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we?With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals.Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.

"Takes readers through the life cycle of bees, their important role in pollination, and presents reasons for their decline... An important resource for all libraries." --Booklist, starred reviewApples, blueberries, peppers, cucumbers, coffee, and vanilla. Do you like to eat and drink? Then you might want to thank a bee.Bees pollinate 75 percent of the fruits, vegetables, and nuts grown in the United States. Around the world, bees pollinate $24 billion worth of crops each year. Without bees, humans would face a drastically reduced diet. We need bees to grow the foods that keep us healthy.But numbers of bees are falling, and that has scientists alarmed. What's causing the decline? Diseases, pesticides, climate change, and loss of habitat are all threatening bee populations. Some bee species are teetering on the brink of extinction."Accessible and concise" (Kirkus), this book will teach you about the many bee species on Earth -- their nests, their colonies, their life cycles, and their vital connection to flowering plants. Most importantly, you'll discover what you can do to help."If we had to try and do what bees do on a daily basis, if we had to come out here and hand pollinate all of our native plants and our agricultural plants, there is physically no way we could do it. . . . Our best bet is to conserve our native bees." --ecologist Rebecca Irwin, North Carolina State University
