Google Earth is a wonderful invention, and not only for people who like to spy on their neighbours. It gives you a perspective you might never have had before. If you’re concerned about green space and housebuilding, for instance, Google Earth can tell you more about the impact of development plans than the sales pitch of the builders or their opponents’ objections. So warning bells should sound when politicians give a broad brush, Google Earth view of society’s ills and then conclude it all needs to change.
