The natural movement of water has long been used to create energy. New forms of hydropower are being researched as alternative ways to create clean renewable energy. This remarkable new book describes how water flow is being used in tidal and wave energy farms, and how the oceans contain enough heat in the surface water to power the world! Case studies highlight the potential advantages and disadvantages of pursuing these different kinds of power.
Because of global warming, nuclear energy is getting a second look. This important book discusses the benefits and drawbacks of this controversial, but clean and reliable, source of power. Case studies show how new technologies are helping make production of nuclear energy safer.
Reducing Your Foodprint teaches children that what they eat and how they eat is important to the environment. The further food travels to get to your table, the more harm to the environment. This enlightening new book explains how to adjust your diet to eat locally and responsibly.
Natural gas, oil, and coal are finite resources, and their use contributes to deadly smog and global warming. The Future of Fossil Fuels follows the world's dependence on these resources and shows how people are working to reduce their useand even make them more environmentally friendly!
In light of the devastating floods in 2010 in Pakistan, Brazil, the United States, and China, this informative book has been newly revised. Floods result from heavy rains and high winds that cause an overflow in water sources such as lakes, rivers, and oceans. Discover how monsoons differ from other storms and how people cope with their devastation.
This informative book has been newly revised in light of the massive eruption in Iceland in March 2010. The skies over a large part of the world were filled with volcanic ash, affecting weather and agriculture and disrupting travel for millions of people for several weeks.
In light of 2008's devastating cyclone in Myanmar (Burma) and hurricanes Fay, Gustav, and Ike in the U.S., this informative book has been newly revised. This book features the science behind these massive tropical storms and how societies around the world cope with their ferocity.
This informative book has been newly revised in light of the devastating tornadoes that have swept across the United States over the last few years. 2008 was particularly fierce with clusters of tornadoes forming every month in the first half of the year.

This interesting book features an examination of the four major groups of fungi: yeasts, toadstools, chytrids, and bread molds. Special sections explore varieties that feed on dead and decaying matter, parasites, and species that form relationships with other species. Case histories involving fungi include penicillin and the fight against disease, and genetically modified (GM) products in food technology.
This book examines bacteria that are found in virtually every environmentincluding those that are characterized by extreme heat, cold, and depthand, of course, bacteria that are found inside our bodies. Case studies examine the development of new vaccines against bacterial diseases and the use of bacteria to help fight pollution.
Some Archaea thrive in extreme places such as in thermal pools, hot vents at the bottom of the sea, extremely salty water, and even in underground oil reserves. This book examines the diverse Archaea kingdom and the division of these organisms by their unusual biology into three main groups. It also explains why little in general is known about them, and why further classification of Archaea is so difficult.
How in the world do you classify the more than one million species in the animal kingdom? This fact-packed book divides animals into the major phyla, classes, and critical features. Fascinating case histories examine the discovery of new mammal species, the need to conserve endangered species, and using natural predators to control populations and preserve species and their environments.
