Pop = bone loss, flame retardant chemicals, hormone interference. Really?

The Today Health website has an interesting post about 5 reasons that you shouldn't drink a lot of pop, or soda if you're from farther north. Some of the reasons are chemicals that interfere with hormones in your body, accelerated bone loss, chemicals that have flame retardant properties, and some potential (in lab animals) cancer causing chemicals.

Read the article and let me know what you think and whether these risks are the result of people finding fault in minor matters or whether you think pop is a health risk. What studies could be done to find answers more conclusively?
