global warming is happening there is no doubt. i do believe that in part it is a natural occurance but i also beleive that it is being enhanced or even sped up by the actions of man.
i do know this one thing i can not survive in a room full of exhaust fumes so they are bad. if they are bad for me they are bad for the enviroment.

i dont pretend to know all about global warming hell i know very little about it actually. but i do know that recycling is not a bad thing. clean air is not a bad thing. so why not try and make the changes that will make this a little cleaner planet?
