approach will work because it is based in the truth. The twentieth century lived in filth. It was much like the eighteenth century before the advent of germ theory, stricken by septic cankers whose origins were shrouded in superstition and miasma. The truth about our physical existence must be shown to people. It must be demonstrated repeatedly and everywhere.

People with networks, websites and sophisticated sensors should not find this task very difficult.

The current industrial base is outmoded, crass and nasty, but this is not yet entirely obvious. Scolding it and brandishing the stick is just part of the approach. Proving it requires the construction of an alternative twenty-first century industrial base which seems elegant, beautiful and refined. This effort should not be portrayed as appropriate, frugal, and sensible, even if it is. It must be perceived as glamorous and visionary. It will be very good if this new industrial base actually functions, but it will work best if it is spectacularly novel and beautiful. If it is accepted, it can be made to work; if it is not accepted, it will never have a chance to work.

The central target for this social engineering effort must be the people who are responsible for emitting the most CO2. The people we must strive to affect are the ultrarich. The rentiers, the virtual class, the captains of industry; and, to a lesser extent, the dwindling middle classes. The poor will continue to suffer. There is clearly no pressing reason for most human beings to live as badly and as squalidly as they do. But the poor do not emit much carbon dioxide, so our efforts on their behalf can only be tangential.

Unlike the modernist art movements of the twentieth century, a Viridian culture-industry movement cannot be concerned with challenging people's aesthetic preconceptions. We do not have the 19th-century luxury of shocking the bourgeoisie. That activity, enjoyable and time-honored though it is, will not
