why not stop overpopulation of the planet which in turn extends all the resources for all the people? I don't care how much solar and wind power you use, or how much biofuel you put in your car - none of it matters because it's just more hot air blowing in the wind. The population is set to increase 3 billion more in short order - that in itself will destroy the resources. It's not the resources we have. It's not just how we use them. It's too many people.
Unfortunately, it's a small percentage of the planets population that consumes most of the resources. Some poor family in Africa isn't using any gas, some moron in LA driving a Hummer is wasting lots.
It can't be hurting people too much despite all the grumbling because:
a) Europeans have been paying these prices for years (and choose to drive more fuel efficient vehicles because of it)
b) People still pass me on the highway going well over the limit so must have money to burn
You don't need to change your car to drive a more fuel efficient vehicle - just plan your trips a little to cut down on the runs you make a shave a few km/h or mph off your speed and you will save money on gas.
