Amidst a world struggling with smart ways to confront climate change, Hawaii's 2050 Plan for sustainability is working to be a model for the rest of the world. So far, it is on it's way to being a leader in solar energy, with Honolulu having the most "solar panels per capita than any other North American city," and the state is working to produce more food locally, as well.

York schools are considering changing public schools into charter schools, following the example of New Orleans and Michigan, in order to help their crumbling school system.
