There was a long period during American history when the general public was largely not aware of the dangers of asbestos. That is no longer the case. These days, most people are aware of the dangers of deadly asbestos fibers, though many erroneously assume the material has been banned in the U.S.
In the late 1970s, when the dangers of asbestos became public knowledge, the U.S. Environmental Protection Agency (EPA), attempted to ban the mining of asbestos and the importation of raw asbestos and goods that contain measurable amounts of asbestos. Unfortunately, this law was overturned by the U.S. Supreme Court a couple of years of after it was enacted on grounds that EPA had overstepped its bounds and did not have the authority to create a law that affects interstate commerce without action from congress.
Today, the asbestos industry isn’t exactly thriving in the U.S., but neither is it dead.
