Some companies like Nestle, H.J. Heinz, and General Mills have started eliminating bisphenol-A (BPA), a hormone-disrupting chemical, from their food packaging. Coca-Cola, however, maintains that BPA is safe and continues to use the chemical in its aluminum cans.

While the government fails to regulate BPA's use, studies continue to point out the chemical's potential health impacts. BPA has been linked to cardiovascular disease, poor sperm quality, diabetes, and early-onset puberty in people. In lab animals, scientists found that the hormone-disrupting chemical triggered breast and prostate cancer.

Coca-Cola should start caring about consumers' health. Ask the company to eliminate BPA from its beverage containers.
