Asbestos is a mineral fiber that was widely used in construction materials, such as insulation, roofing shingles, floor tiles, and cement. It was popular due to its durability, fire resistance, and insulation properties. However, asbestos is also hazardous to health, especially when it releases tiny fibers that can be inhaled into the lungs.

Exposure to asbestos can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. These diseases can take years or even decades to appear, and there is no cure for them. Therefore, it is crucial to handle asbestos with care and dispose of it properly.
