not to sound like a tree hugging hippy. But you are already experiencing some of whats going on with our ecosystem. Bad storms have been on the rise in the past few years, our world is changing.
Our cars are not the problem, its the amount of people that are the problem. Check out this chart stating historical data of the US Population: http://www.census.gov/popest/archives/1990s/popclockest.txt
more people = more waste
lets unfreeze hitler and get him to kill off all the people that do not contribute to the US. I think we would make less waste, less pollution and change the way the world is.
But yeah, lets worry about emissions instead of population control
