Asbestos is a naturally occurring mineral that was widely used in construction materials until the 1980s. It was favored because of its heat resistance, durability, and fireproofing properties. However, we now know that it is a dangerous substance that can cause serious health problems, such as mesothelioma, lung cancer, and asbestosis.

Asbestos can be found in a variety of building materials, including insulation, roofing, flooring, and pipes. It is important to properly dispose of these materials to prevent the release of asbestos fibers into the air, which can be inhaled and cause health problems.
