With fossil fuel prices escalating and countries searching for ways to reduce oil dependence and greenhouse gas emissions, capturing the earth's heat for power generation is garnering new attention. First begun in Larderello, Italy, in 1904, electricity generation using geothermal energy is now taking place in 24 countries, 5 of which use it to produce 15 percent or more of their total electricity. In the first half of 2008, total world installed geothermal power capacity passed 10,000 megawatts and now produces enough electricity to meet the needs of 60 million people, roughly the population of the United Kingdom. In 2010, capacity could increase to 13,500 megawatts across 46 countries-equivalent to 27 coal-fired power plants.

Animal researches have long been puzzled by certain aspects of elephant behavior. In particular they have wondered how apparently random group of elephants, sometimes separated by miles, can manage to move in a cohesive, coordinated manner toward the same destination. Equally mysterious is how, without any discernible means of communication, male elephants are able to track down a female in heat even if she is many miles away.

Just How Many different kinds of living things exist in the world is question people have been trying to answer for more than 2,000 years. One of the first to attempt an answer was the Greek philosopher Aristotle, who died in 322 B.C. He identified about 1,000 different species of plants and animals .
