Wildlife Monographs - Dolphins
Dolphins are highly evolved and social animals, with their own language of clicks and whistles and elaborate courtship rituals. Their obvious curiosity about the world extends to humans, if only for a few moments of fun, but unfortunately this factor of their intelligence has made them targets for exploitation. Add that to pollution, toxins and the practice in some cultures to kill them for food, dolphins, while not yet an endangered species, are continually threatened.
Prepare engaging weather lessons, from short topical units to year-long weather tracking projects. Basic factual material about weather patterns and such weather phenomena as thunderstorms, tornadoes, hurricanes, heat and cold waves, floods, and droughts, are covered along with such hot topics and issues as global warming, air pollution, acid deposition, and ozone depletion. Thorough, balanced, and comprehensive, the sourcebook serves equally well as a ready-reference and a planning tool.
What is pollution and why is it important? Why does pollution occur, and is it harmful at all levels? What happens to pollutants in the environment? What are the root causes of pollution?
Inventor and futurist Ray Kurzweil foresees the dawning of a new civilization where we will be able to transcend our biological limitations and amplify our creativity, combining our biological skills with the vastly greater capacity, speed and knowledge-sharing abilities of our creations. In practical terms, human ageing and illness will be reversed; pollution will be stopped and world hunger and poverty will be solved. There will be no clear distinction between human and machine, real reality and virtual reality.
Dictionary of Mining, Mineral and Related Terms 2nd Ed.
The second edition, containing 28,500 terms, incorporates the technological developments and environmental regulations that have changed the minerals industry so dramatically. It is the culmination of a 5-year effort incorporating not only standard mining-related terms but also terms in peripheral areas, such as the environment, marine mining, leaching, pollution, automation, health and safety. Many of these terms now have a legal definition based on law or regulation.
