Cities are 2% of the earths crust, but they are 50% of the worlds population.

Carlo Ratti

Fifty percent of the world's population lives in cities. In a couple of decades, 70 percent of the world's population will be living in cities. Cities are where the problem is. Cities are where the solution is, where creativity exists to address the challenges and where they have most impact. This is why, in 2005, the C40 was founded, an organization of cities that address climate change. It started with 18 cities; now it's 91. Cities simply are the key to saving the planet.

Michael Bloomberg

Paul Theroux

A sound Physics of the Earth should include all the primary considerations of the earth's atmosphere, of the characteristics and continual changes of the earth's external crust, and finally of the origin and development of living organisms. These considerations naturally divide the physics of the earth into three essential parts, the first being a theory of the atmosphere, or Meteorology, the second, a theory of the earth's external crust, or Hydrogeology, and the third, a theory of living organisms, or Biology.

Jean-Baptiste Lamarck

Henry A. Kissinger

You must love the crust of the earth on which you dwell more than the sweet crust of any bread or cake. You must be able to extract nutriment out of a sand-heap. You must have so good an appetite as this, else you will live in vain

Henry David Thoreau

The use of refined petroleum as fuel, which began in the 1850s, freed hundreds of millions of people from the toil of centuries, gave hundreds of millions more a life of ease and plenty, and, by allowing great cities to feed themselves from every corner of the world, multiplied the population of the earth fivefold.

Our fifty principal cities contain 39.3 per cent of our entire German population, and 45.8 per cent of the Irish. Our ten larger cities only nine per cent of the entire population, but 23 per cent of the foreign.

Josiah Strong

I think America may be growing up and accepting the fact that the bulk of life exists beyond 50. Because demographically... the vast population is over 50.
