A study was recently completed by researchers at the University of Illinois - Chicago which establishes a link between the rise in internet use and gaming to a decline in camping, fishing and other outdoor activities. Maybe a bit obvious, but sad in many respects. An article in the Houston Chronicle talks further about how enjoying nature has become virtual for many and is an obvious cause of the rise in childhood obesity. There is even some suggestion that those who do not enjoy nature and what it has to offer, may care less about the environment.
Even if nature is not accessible to all (you can safely say that not all people live near a national forrest nor have the means to visit one), I feel that gardening is another way to connect to nature. I have some issue with a comment made in the Houston Chronicle that yet agin stereotypes Gen X and Y'ers as not connected to nature. Yes, maybe true for some, but I find that consdition accross all generations. As a Gen X'er I think that connecting to nature and a love of gardening often times has more to do with upbringing and influences in our lives as we grow and mature.
For me, gardening is therapy, a time to get away from the barrage of modern life and a chance to have a hand in creating art in the garden. One can only hope that this trend is an anomaly.
