While the United States has yet to ban the mineral, it is one of the only world powers without a ban. Nonetheless, its uses are restricted, and removing it from a home or building is not an act likely to be undone anytime soon. The restrictions began when asbestos’s dangers were first announced in the late 1970s. Maddeningly, they were known of before that, but for economic reasons, were kept a secret. The general public was not made aware of the dangers, but a few people discovered them for themselves, and in keeping it secret, effectively killed thousands of people.
