Silicosis is typically caused by years of breathing in silica dust at work, and can worsen even after work exposures stop. In recent years, after decades of inaction, the federal government finally took several important steps to reduce the incidence of this ancient and debilitating disease. Under the Trump administration, all that progress is going away, in but one example of the widespread destruction now taking place across the federal government.

Silicosis first caught the attention of the federal government in the early 1930s, when hundreds of workers hired by the chemical company Union Carbide and its subsidiary to drill a tunnel through a mountain of almost pure silica died of silicosis. Most of the workers were Black, and many were buried in unmarked graves. President Franklin D. Roosevelt’s secretary of labor, Frances Perkins, issued a report on the widespread problem across factories and mines, informing businesses that control measures, “if conscientiously adopted and applied,” could prevent silicosis.
