big business owners advertise like oil was going to be around forever:
I have seen planes like the ones above, as recently as today (May 11, 2008) pulling banners behind them advertising sports teams like Utah’s Jazz (basketball) and the Bees (Baseball).
I think we should be calling these people and getting on their cases about this. What an irresponsible, wasteful thing to do!

As oil gets more and more expensive it will be less and less profitable to run ads like that.
Also, what do you think about hemp for biofuel instead of corn?
