This article by the UK Daily Mail gives an example of how kids today are given fewer opportunities to roam in nature than past generations. I know as a kid, I loved playing outside and didn't have to be driven 20 miles to do so. I could just go outside and play in my neighborhood, and was free to roam about until my mom called me home for dinner. Now, living in the middle of a major city, I rarely see kids outside playing, and I can't really blame them. There is nowhere for them to go, everything is paved, people don't seem to know their neighbors (I know we don't), yards are smaller than living rooms, and busy parents have to drive the kids to the nearest park for the kids to play.
