The benefit of writing a column about solutions is that it provides an alternative lens through which to view the world. The daily news tends to be dominated by daunting challenges (unemployment, climate change, the polarization of Congress) and flashpoint events (the killing of Osama bin Laden, the tsunami in Japan, the Penn State scandal). These stories are vital to cover. However, people often come away from the news with a lot more information about problems than about how society is dealing with them.
