Final answer:
Asbestos fibers are hazardous when inhaled, causing lung cancer, mesothelioma, and asbestosis. This material was extensively used in the past for its durability and heat resistance, but its airborne particles pose serious health risks. Asbestos use is now banned or regulated in many countries.
Step-by-step explanation:
The fibers of asbestos are dangerous when inhaled because they can lodge in the lungs and intestines, leading to serious health conditions, including cancer. Asbestos was widely used in construction and manufacturing due to its fire properties and strength. However, when asbestos-containing material is disturbed, the fibers can become airborne, posing a significant health risk. Exposure to asbestos can result in lung cancer, mesothelioma, and asbestosis, among other diseases. The use of asbestos in new products has been largely banned or highly regulated globally because of these health risks.
