If I had a trillion dollars.
In the report Infrastructure 2007: A Global Perspective, published last May, the Urban Land Institute (ULI) and Ernst & Young assess the state of the world's infrastructure as we reach a turning point in world history: For the first time, one out of two people on the planet lives in a city. Now more than ever, effective systems of public infrastructure are crucial for societies' health as populations grow and resources are squeezed. But in many countries, including the United States, public infrastructure is underfunded and under strain. The ULI estimates that it would cost $1.6 trillion to make needed upgrades to America's infrastructure.
My favorites are somewhere between Yung Ho Chang, Anne P. Canby and Kunstler.
