Narrowing My Focus

This post will narrow the broad range of questions I generated for my last post, down to only a few that are most important to answer to continue my participation in this controversy.

Where in the world do the highest concentrations of space exploration supporters and opposers live?

I think this question might give insight into what kinds of people hold which belief. For example, it might turn out that just the richest nations want to explore space ( which wouldn't bee too surprising) or, maybe it's evenly distributed around the world - who knows for sure?

What are some real, legitimate problems with space exploration, that cause serious reason not to continue space exploration?

This is a serious one, because I have yet to hear a reason that has made me think, " you know? That makes sense, I wonder if space exploration is worth it..." But it might be because i'm biased. If, however, I can find one, it would help my credibility, and I wouldn't be stuck in the dark.

What is the public opinion on space exploration?

I added this one ad hoc, because I don't think I'll be able to find anything on where people support each side from. But this one should give some hint as to how many people would be in my audience.
