Asbestos

There is little debate about the dangers of this silicate mineral fiber, once commonly used in insulation, fire retardant materials, and other construction elements. Asbestos fibers are invisible to the naked eye, and when disturbed they can be inhaled, causing serious harm, including lung cancer and asbestosis, which is damage to lung tissue. Asbestos is still present in numerous construction elements, particularly in older buildings; to limit exposure, special care must be taken in its removal. Children are especially vulnerable, and asbestos-related disease can take years to manifest itself, so evidence of the material in older schools is of particular concern.

Word of the Day
   Green roof

You might call it a living roof, an eco-roof, or even a rooftop garden; in every case it's a roof that has been planted with vegetation. And while it's literally as green as the plants that grow there, it's also "green" in the Earth-friendly sense: The plantings can serve as natural insulation, reduce sewage system loads and air pollution, and counter the "heat island effect" (raised temperatures in urban areas). The roof is typically covered with a layer of waterproofing material, then with soil or another planting medium, and planted with grasses, flowers, groundcover, or even shrubs and trees. Irrigation systems are sometimes included. However it's designed, it sure beats old-fashioned black tar on a hot city day.
