Agora que os problemas ambientais nos levam a supor um alto aquecimento da temperatura do Planeta e as consequências que vamos todos sofrer em um futuro muito próximo, podemos buscar algum ensinamento nos fatos passados, como por exemplo nas chamadas "Dust Bowls", entendidas comumente como as tempestades de areia, que varreram o centro-oeste americano na década de 30 do século passado.

John Steinbeck escreveu sobre o que as pessoas sofreram, na sua novela de 1939, The Grapes of Wrath:

"And then the dispossessed were drawn west- from Kansas, Oklahoma, Texas, New Mexico; from Nevada and Arkansas, families, tribes, dusted out, tractored out. Car-loads, caravans, homeless and hungry; twenty thousand and fifty thousand and a hundred thousand and two hundred thousand. They streamed over the mountains, hungry and restless - restless as ants, scurrying to find work to do - to lift, to push, to pull, to pick, to cut - anything, any burden to bear, for food. The kids are hungry. We got no place to live. Like ants scurrying for work, for food, and most of all for land."

A continuarem as atuais condições de progressivo aquecimento, nossas cidades vão se tornar um pesadelo onde o ar-c0ndicionado não será suficiente para, literalmente, nos tirar do sufoco.

A planetary culture that does not develop spacefaring is courting suicide. All our history, all our social progress and growing insight will be for nothing if we perish. No risk of this kind, however small it might be argued to be, is worth taking, and no cost to prevent it is too great. No level of risk is acceptable when it comes to all or nothing survival." Gregory Benford and George Zebrowski, Skylife, 2000. "We must turn our guns away from each other and outwards, to defend the Earth, creating a global and in space network of sensors and telescopes to find asteroids that could destroy our planet and create the systems to stop them. It makes no sense to dream great dreams while waiting to be hit by a train." Buzz Aldrin and Rick Tumlinson, Ad Astra Online, 2006. "The question to ask is whether the risk of traveling to spa...
