Yikes! 7 April 2001
Philippe Crist of the OECD in Paris, until recently with their EST! Environmentally Sustainable Transportation program draws our attention to this series of images of NASA's Earth Observatory. He points out that this map vividly illustrates where the sources of today's emissions can be found. Though it maps city lights, is will do just as well as a vivid reminder of automotive emissions.
Where is the problem today?
This is one of a cycle of images created by
Marc Imhoff, a biologist at NASA’s Goddard Space Flight Center. For the past six years, he and a team of researchers have been looking for ways to measure the effects of urbanization on the biological productivity in the U. S. and other countries around the world. They created a method of mapping urbanization on a countrywide scale by using satellite images of the light cities generate at night. With the resulting city lights maps, they are now zeroing in on the impacts urban sprawl has on the food we eat, the air we breathe, and the ecosystem within which we live.
Very telling reminder of who is doing what to the planet, Philippe. Thank you.
