Here is a video of silica sand dust in the lungs.
Below shows frac sand dust blowing from a loading facility in the middle of Tomah, Wisconsin. This dangerous dust is entering the lungs of all residents of the city. The frac sand industry has been given a green light in Wisconsin to put all people, animals and life forms at risk so that mega corporations can make billions. Western WI is a sacrifice zone. It is our duty and responsibility to stand against this industry.
