Asbestos is a fibrous material that was commonly used in building materials due to its strength, resistance to heat and fire, and durability. However, it was later discovered that asbestos can cause serious health problems such as lung cancer, mesothelioma, and asbestosis. This is why it is important to have asbestos removed from buildings that contain it.

Asbestos can be found in various building materials such as insulation, roofing, flooring, and siding. It can be dangerous when it is disturbed or damaged, as it releases fibers into the air that can then be breathed in by people. This can lead to serious health problems, especially if the exposure is prolonged.
