I'll buy that it's the top seller, but are the majority of bottled drinks water? Because when I go to a convenience store there is usually one fridge for bottled water and several for all the other stuff (soda, tea, juice, Gatorade etc).

I don't think all of that really matters anyway, because the point I'm making is: anything that's bad about a plastic bottle filled with water surely must be just as bad for a plastic bottle filled with water and a little bit of sugar and coloring. Nobody has really addressed this, and I just think it's strange.

I'm fine with the idea that we should address this by drinking tap water instead of bottled water. All I'm saying is that surely the same goes for other bottled drinks as well.

I don’t believe your last sentence is correct in the case of brands like Dasani that are just filtered tap water. And for drinks other than water the bottles still have to get made and disposed of. Again, they are all just bottled water with a little bit of extra stuff in them, so whatever impact bottled water has, they all must have as well.
