sure, it bothers me.  i certainly hope that images of african and asian privation will drive a bit of conservation here.  if there is a hummer backlash now, when cost and (hard to visualize) global warming are the drivers, i sure think it would be stronger when the image becomes starving people.
Yes and no. It'll depend on the complexion of the starving people, unfortunately. Do you think that closet Ku Klux Klan idiots down south are going to care about starving Africans? Worst case: David Duke. Do you think he'll care that Africans are starving so he can get a load of bio- jet fuel for his Lear Jet? Or the others who time-share that plane?

By far the most egregious wasters of energy are the corporate kingpins who exploit illegal aliens and fire them once injured on the job, especially in Texas. Are they going to care who starves - of ANY colour - so they can get a fill-up for their jet?

we're back again to human nature, or each of our expectations of human nauture.

i notice that "doctors without borders" ...

"In 2004, MSF's worldwide income was $568 million. In the United States, nearly 380,000 private donors contributed more than $91 million to MSF-USA."

that wouldn't happen if the glass was truly empty.

A 'hummer backlash' today, with small-car drivers sneering at hummer owners, may someday become a 'mechanized transport backlash' with those of us walking (or lucky enough to own a mule) sneering at those gluttons with the plug-in hybrids. It's a matter of perspective here...
shrug.  and the hybrid might be the car that stays in the garage while you walk for most trips.  It's a matter of perspective here...
