BPA-Free Plastics Linked to Adverse Human Health Effects
A new investigation by Mother Jones magazine finds that plastics free of the controversial additive bisphenol-A (BPA) may actually be more harmful to humans than those containing it. Meanwhile, scientists continue to debate what doses of the chemical are harmful. We'll discuss the latest news on the controversy over plastics, ...Read More
