Nature – Stephen Kellert
“The typical child in the United States now spends 90% of the time indoors. US children aged 2–5 engage in electronic media for an average of more than 30 hours per week; for 8–18-year-olds the figure is 52 hours. Most children devote just 30 minutes daily to unstructured outdoor play; a generation ago, it was more than 4 hours…A growing body of evidence from US, European and Australian studies…suggests that this disconnection may be causing physical, emotional and intellectual deficits in children’s learning and development…contact with nature remains vital to child development, and it may not be possible to find a substitute.”(more)
