Currently, the United States educational system is in a transitional phase. It is trying to have the best of both worlds: high test scores, and active students. Students can't read while running, and they can't run while reading. Louv describes where the educational system was before: Little time outdoors as students focus strictly on their studies. This is apparent in the quote: "many districts considered recess a waste of potential academic time or too risky"
Economists and doctors have proven that an active lifestyle in children and adults is not only beneficial for a child's physical health, but also for their mental health. Releasing energy in the outdoors can help kids focus better in class. Louv explains how useful a therapy nature is for ADHD (Attention Deficit Hyperactivity Disorder). I personally think that the over-diagnosis of ADD and ADHD is a terrible burden on society. Overmedication of children will, in my opinion, cause severely negative long-term effects on not only the children themselves, but on a societal level; as is mentioned in the text, "Critics charger that often-perscribed medications....are over prescribed, perhaps as much as 10 to 40 percent of the time."
The text cites that the cause of this over-prescription is due to rapid urbanization. Children in cities don't have as much ability to release energy, causing hyperactivity. I think that this is one small aspect, but I'd consider the real culprit of overmedication and overprescribing ADHD is that adults refuse to let children be children. They want to run around, they want to  be free from the constraints of a classroom.
Further reading, however, emphasizes data that does link thinking more clearly and being in nature, so I suppose I was incorrect in assuming no link... "...those who had walked in the nature preserved performed better than the other participants on a standard proofreading task. They also reported more positive emotions and less anger." I personally don't have ADHD, and I personally find more solace in front of a computer screen than in front of a pristine lake. But maybe that's just me. Now that I think about it, it may have been my prevalence to go outside and play around in the woods next to my house that kept me from being diagnosed with ADD or ADHD. But that's just anecdotal evidence.
