Crystalline silica is found in everyday materials, but it can cause health problems for workers exposed to it on a regular basis.
BERLIN, Ohio - Amish communities in Ohio and Pennsylvania are debating a temptation -- the large cash royalties that can come with the boom in oil and gas drilling from the technology known as fracking.
Jerry Schlabach, an Amish resident of Berlin, Ohio, says that just as with any other community big money can bring spiritual corruption. But he believes that if the Amish use the wealth wisely, the drilling boom could be a positive thing.
Historian Donald Kraybill says some Amish accept drilling because they have a strong sense of God's creation, which includes oil and natural gas. He says that if the Amish can find ways to capitalize on such resources, they don't see a problem with that.
