RJA #3b: Narrowing Research Topic

I don’t think I need to narrow my topic as a whole, but I do need to narrow the focus. I think I want to focus on just drinking bottles and the major company makers. How they have capitalized on the BPA heath controversy by making new products and doing voluntary recalls. I want to explore the heath argument going on about BPA, but also want it to tie into how a huge product focus is on bottle companies and what they are doing.
