The document discusses how increased screen time and lack of outdoor time for children has led to issues like increased obesity and mental health disorders. It proposes that a new mobile app called Nature Passport could help address this by using gamification and geocaching techniques to motivate kids to get outside and engage in outdoor educational activities that integrate science and math. The app would be developed by organizations like IslandWood and Nature Play Australia and would have a soft launch at the 2014 World Parks Congress in Sydney.
