Asbestos
Asbestos is a naturally occurring fibrous silicate mineral and after years of research, it has shown that exposure to asbestos can cause cancer and other serious diseases. Asbestos played a huge role in American commercial product manufacturing in the 20th century. Americans who worked in construction and other blue-collar industries were most at risk of being exposed. Asbestos has been banned in more than 60 countries, but not the U.S. About 1.3 million U.S. workers in construction are at risk of being exposed today.
