How well do you know the world? Your years of experience build into insight. You devoted hours beyond count to studying it in school: you can recite highlights of its history, outline its geography from polar ice to tropical forest, appreciate its cultures. You can explain how it depends on photosynthesis. You know about climate change. Maybe you can quote reliable stats on the world’s refugees.
But – surprise! -- there are ways to see the world you’ve never dreamt of.
