n. A sedentary lifestyle focused on screen-based activities, particularly television, the Internet, and video games.
Numbers tell us people don't participate in outdoor activities the way they once did. … Visits to national parks are down, as are fishing, hunting and even watching wildlife. Only 25 percent of the population — down 18 percent — participates in an outdoor activity.

Scientists call it "videophilia" — a way of life connected to computers, video games and TV.

Struggling orchestras or theatre companies are one thing. But when you hear about golf course operators trying to offset decline with special marketing packages aimed at women and families or trying to recruit young people through high school outreach programs, you begin to wonder what's really happening here.

Is this all part of a broader trend? Is it a shift in interests that is talking place, or is it a general withdrawal from activities outside the home?

Demographic trends such as an aging population have been mentioned as part of the explanation, although this could just as easily be a growth factor for leisure activities such as golfing, fishing, going to the theatre or a symphony concert.

The reports on nature-oriented recreational activities losing their appeal emphasize the concurrent rise of "videophilia" — a shift to "sedentary, electronic diversions such as playing video games, surfing the Internet and watching television" as a primary factor.

We have presented data suggesting that as sedentary recreation choices involving electronic media become more prevalent and the cost of motor vehicle travel rises we may, unfortunately, predict further declines in per capita NPV. If it is indeed true that people have changed their behavior, that they go to national parks less (at least in part) because they are more sedentary and use electronic media more, what does this mean for biodiversity conservation in general? There would seem to be at least two possible biodiversity conservation-related viewpoints. One viewpoint might see declining per capita NPV, and the resulting reduced ecological pressure on our national parks, as being a good thing. An opposing viewpoint might see people’s apparent decrease in ‘biophilia’ and corresponding increase in ‘videophilia’ (which we here define as ‘‘the new human tendency to focus on sedentary activities involving electronic media’’) as being a very bad thing indeed.
