General Discussion

That sounds like a good start. Seeing as how we're gauging citizens' sustainability choices, a dependent variable could very well be the lifestyle that people choose to live. While the opinions that one holds would be astrong influence on the choices people make, I'm wondering if the range of independent variables should be widened, at least while we're still in this preliminary stage of survey-making. We could possible consider that "convenience", "prices/cost", or other factors may have as much as an influence as "opinion". :)
