In recent years, mold and mildew have been widely publicized. The media has alerted Americans to the possible health risks of certain types of mold. Local and national news, television and radio talk shows, and the Internet have all contributed to the growing fear of mold and mildew. Scientists and doctors have weighed in on the potential health hazards of mold.
Molds are part of the natural environment. Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees. The growth of mold indoors should be avoided. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air. Mold may begin growing indoors when mold spores land on surfaces that are wet. There are many types of mold, and none of them will grow without water or moisture.
