In this Nov. 12, 2019 photo, Gayla Benefield stands outside her home in Libby, Montana. Benefield was among a very few people who raised public concern in 1999 about asbestos-related lung disease that was killing workers at the W.R. Grace vermiculite mine in Libby and, in some cases, family members. Benefield's father, mother and husband have died from the disease that is also killing her and four of her five children. She says she may have been the least-liked person in town, but 20 years later she says some people are coming around and have thanked her quietly. (Casey Kreider/Daily Inter Lake via AP)
