Summary-Nanotechnology May Aid Environment
             Nanotechnology is considered a clean technology, also a key to solving some current environmental problems. The field of nanotechnology is rapidly growing. The time has been cut from five to ten years down to two or three years, according to Mihail Roco, National Science Foundation's senior adviser. Nanotechnology will have such a strong impact on the way science deals with medicine, food, electronics and the environment, that within a decade, it is seen to have a $1 trillion yearly market in the products that carry nano-components.
             With the worlds population expected to reach more than 11 billion by the year 2050, nanotechnology is believed to be able to allow governments and industry to keep the planet livable, by cutting down on waste and helping to provide sustainable food, water and energy. The NSF has been studying nanotechnology's potential environmental benefits. For example, filter systems for drinking or wastewater, natural gas pipelines and smokestacks to remove even the smallest impurities. For water, it means much cleaner drinking, for gas, it means finer filtration for cleaner burning, with less smog. Industrial plants may also me able to use more sensitive emission "scrubbers" that serve as protection against even nano-sized pieces of soot from waste gases.
             Nanoparticles are also being researched for use as sensors to monitor air or drinking water for the presence of toxins. Further more these sensors can be networked to give a full description of the environment and any encroaching pollutants, even chemical or biological weapons. Along with this study pollution-absorbing nanoparticles can be used to clean up tainted water or soil.
