If we could design cities & buildings a little better, we would not need so many cars, trucks & SUV's. I blame the global warming on the modern world, namely the US. Sure, this COULD be a natural state of temperature fluctuations, its doubtful.
This world is based on use & throw away, have you ever visited your cities garbage dump? Its really depressing... not only that, though we are multiplying like rabbits, filling up this Earth. There basically is nothing that will stop us, until we kill the earth. we're like those microbs in a petri dish, they multiply like mad, and use up all the resources.
War in Iraq, no its not for oil </sarcasm>, everyone is running out of resources, and there will not be a substainable alternative energy source... sorry. What we need to do, is to revamp our thinking, the future is not going to be about how to get somewhere, though how to stay in one place, grow our food locally and provide for ourselves in smaller groups.
Of course this is not human nature, to be content with that, you know, "bigger is better". Sorry for the dooms day outlook, I just can not see a sunny day with our current practices in life. Though it could be good in a few aspects.
People would be forced to stop spending on credit cards, paying over seas workers to assemble our crap. We would inevitable start using things like coffee mugs instead of styofoam, and stop eating McDonalds, as transport is too expensive. Local Farmer's hire farm help, shoe makers come back to local areas, it will be an all new economy, locally based. That would be worth while, putting more people to work locally, creating a real town & downtown center...
gasp, someone may have to "walk" to their store! Of course, this would still be a treck, across our 6-8 lane hiways, thogh expect local neighborhood stores to make a come back too...
