Out Break of Cancer in the Acreage

I think that these children like all children are being exposed to a variety of chemicals that can cause cancer. One of the places that they come in contact with very dangerous chemicals is when they are playing sports on fields treated with a wide variety of chemicals. Tell me what child doesn't bite their fingernails when they are sitting on the side lines during a game. The ball is in constant contact with the ground and then handled by the children. We need to do some tests on the balls that are being used on the fields to see what chemicals that they are picking up.
Second every parent should know what chemicals the superintendent of that field is using and ask him to supply the MS DA sheet explaining the hazards of those chemicals. I just don't understand why we have to use these chemicals when there has been organic solutions for century's.
