Asbestos is a naturally occurring mineral made up of thin, fibrous crystals. It was widely used in construction and manufacturing due to its heat resistance, strength, and insulating properties. Common applications included insulation, roofing, and fireproofing materials. However, exposure to asbestos can lead to serious health issues, including lung diseases and cancers such as mesothelioma. As a result, many countries have restricted or banned its use. Safe removal and disposal of asbestos-containing materials are crucial to protect public health and the environment.
