Today I decided to go to a location, that ended up taking 1 hour and 20 minutes.

I cycled on some normal rodes, and also on a freeway.

About 20 different times on the commute I realized how bad the air was...many times when a huge truck came by, and other times smaller trucks.

I realized, and after reading some threads on this board, am I getting a health benefit from cycling? Or, am I actually jeopardizing my health from being on the road?

It doesn't seem fair, that when your trying to reduce pollution, and be healthier, by walking or biking, that you get to breathe in someone's fumes. Especially those huge trucks...

I'm becoming really fed up with it all...honestly. I wish things would change. There are studies that show diesel causes cancer...so WHY IS IT STILL ALLOWED!???

Are people ignorant??!? WAKE UP WE NEED TO CHANGE!

Something needs to change. I think maybe having a gasoline tax is the solution, as well as outlawing things that cause cancer! It only makes sense.

I'm so sick of this ****. Why should I be punished for trying to do something good for myself and other people. When I bike or walk, I'm not creating a bad environment for a car driver, but they get to cause a bunch of noise and air pollution for me. Its not fair, and if things don't change, no one is going to want to ever go outside again.... People will stay inside all day, because the outside world has been overtaken with huge levels of noise from engines, and huge levels of pollution.

I live in ****ing San Diego, one of the best weather places in the country. And still, you don't see a lot of people outside. Its SAD. Why? Because the second you step outside, you see roads. Roads, that are filled with these metal boxes that fly by, creating a ton of noise, that is not harmonious to the ear. You don't want to be around them. And on top of that, they create a bad environment to breathe.

I'm pissed off that people before me, haven't done more about this ****. I'm 23. Thanks a lot to all the older people here, that were too stupid too realize the ****ing harm cars cause to our society. Thanks alot, for moving out to the suburbs, then whining about how you need more freeways, only to drive your ****ing SUV even farther and longer.

Thanks alot... for only thinking of yourself, and not having a ****ing sliver of a conscience to think of your environment, and the impact of your actions.

Its now on our generation to change things, to deal with the ignorance of too many people.
