Artificial turf fields - Crumb Rubber harmful?

Athletes from all sports are familiar with turf fields.  At this day in age, I have even played on a turf baseball field.  These turf fields are made of crumb rubber.  Crumb rubber is car and truck tires shredded down to fill in the space between the artificial grass and the surface of the field.  There is many health concerns with these new turf fields.  One of them is heat.  On a hot summer day, the crumb rubber spread all over the field can absorb and reflect heat.  Temperatures taken 3-4 feet above the surface of the field have been measured to be, on some days, 130-140 degrees Fahrenheit.  That is right at the height of a child that may be playing on the field.  This heat is not only harmful to a full grown person, but to a kid it could be deadly.

Another health hazard that comes from these fields is the risk of cancer.  There is a direct link between soccer goalies and cancer.  The small black pebbles we call crumb rubber is to blame for the cancer patients.  As a soccer goalie, you are rolling around and sliding on the turf the most.  I know from my very little experience as a soccer goalie, that when playing on turf, the turf crumb gets everywhere.  I can remember getting in the car after a game and while getting out seeing all the crumb that has been stuck to me left behind.  Although there is no real scientific evidence that suggest that turf crumb causes cancer, there is a direct link between soccer goalies playing on turf and cancer.  Cancer is not something that should be messed around with.  Athletes need to open their eyes and realize these beautiful fields are causing them harm.
