Google Earth can be viewed as a “browser” for people who are visually and spatially oriented. It lets them access information from around the world, using the planet itself as their visual/spatial reference point. For our new Project Happiness, we are anticipating we’ll receive posted video, audio, photos and other artistic contributions from schools and students around the world, and Google Earth will be one of the “portals” that people can use to sort out this information.
To find examples of Google Earth being used by nonprofits, check the Google Earth outreach web site. There are many, many specific example on the outreach showcase page.
The ways I choose to get regular exercise are hiking and biking. I never could stand “going to the gym” and doing an indoor workout. It always seemed to me that there was little point in getting in the car, driving somewhere, parking, going inside to exercise on machines, getting all sweaty, then back in the car, and driving home again. And running was always hard on my feet and knees, so although I did run for a few years (up and down San Francisco hills), it didn’t really last.
