good point!I believe that humans of course have an effect on the planet and pollution is harmful but I also think the planet goes through natural cycles of cooling and warming, and there is nothing we can do about it.
I do hate SUV's but only because a soccer mom doesn't need a Hummer to drive her kids to practice, a van would do the job plus I have a small car and when I am turning left they stupid idiots who drive them always block my view. I know they can see just fine in their big ass car if they just stopped a few feet back.
Hummers are more of a issue than beyond the environment. They are one of the main things wrong with the American auto industry today and one of the reasons why they are in their current situation.
For one most people can't afford them, even the people who buy them.
