All your interviewee choices seemed well planned and thought out. I like that you focused on collecting stories- for example, the added cost of a vegetarian choice at the camp, a decision made like it was a fashion statement.
I wish you dug even more into environmentally friendly snack foods. Your observation that people don’t think/care about environmentally friendly snacks is an important insight into our society’s choices to focus on short term rather than long term benefits/costs.
You have a strong concept, looking for creative ways to address environmentally friendly snacking. What if you played with weaving people’s de-prioritization of environmentally friendly food consumption into a problem statement?
