Asbestos is a mineral fiber that was used extensively in the construction and manufacturing industries during the 20th century. It was primarily used for its insulating and fire-resistant properties in buildings, ships, and factories. Asbestos was also popular in automotive brake linings, vinyl floor tiles, and various other consumer goods.

However, in the 1970s, the dangers of asbestos exposure became apparent. It was discovered that asbestos could cause a range of life-threatening illnesses, including lung cancer, mesothelioma, and asbestosis. Despite this knowledge, asbestos continued to be used well into the 21st century, and it can still be found in many buildings today.
