I like both of your ideas. I like that you highlight not only choices that people must make in their own lives, but also in their communities as we must understand that dealing with climate change is not only an individual battle, but one we must make as a community as a whole -- local and global. The second idea you have listed is a very important topic, and I can see it as very poignant as it might bring in very important societal and political implications.
