Global Cities at Tate

Tate Modern has gone all green and demographic! I saw this item on BBC News last week, but Tate Online hadn't been updated to include Global Cities, which continues in the Turbine Hall until 27 August 2007. Free! As an art show it's a non-starter, but as a means of displaying statistics with the maximum visual impact it's excellent. Did you know that 50% of Earth's population now live in cities and that cities emit 75% of our carbon emissions? So you can't blame global warming on cow farts (a Brit. preoccupation)! How many cows do you know who live in a city? Lego-style models of the top 10 cities show the density of human populations, with photos and art displays to illustrate aspects of city life. The most surprising fact is that twerps like President Bush aren't as important as we thought. How we tackle global warming is in the hands of city mayors, not presidents.
