Latest media reports show manufacturers are using used tires, cables, even plastic wastes as raw materials to make synthetic running tracks and sports fields. Along with this revelation come new suspicions and confusions. While some insist industrial wastes like used tires are prohibited from such uses, others say industrial additives, not raw materials, are mainly to blame for the "toxic" running tracks and sports fields.

But who do we believe?

Are those scared, angry parents, who have called for competent authorities to step in and clarify, over-reacting? Are schools, which are demolishing such tracks, closing sports facilities, even entire campuses, over-reacting?
