Live like a caveman to cure depression and global warming?

The idea of living like a caveman to cure depression makes a lot of sense to me and also Psychologist Stephen Ilardi. Not that I have been pondering about it a lot, but if you skim the surface for a second, and not judge me as a lunatic, answer me this, what are people most commonly depressed about? Working, paying bills, going to school, lacking sleep, not spending enough time with loved ones... just to name a few. I can't imagine the average caveman having these types of problems on his/her daily basis.

Maybe we've been wrong about depression. Maybe it's not just some mental-chemical problem requiring a Prozac prescription or soulbaring confessions to a Dr. Melfi-type therapist. Maybe, says Stephen Ilardi, Ph.D., an associate professor of psychology at the University of Kansas, what's darkening our lives is the way we actually live our lives....
Since World War II, as the United States has modernized and grown more urban, depression rates have risen tenfold. Nearly a quarter of to day's adult population will have experienced the disorder by age 75. Ilardi wants us to look back, way back, to our Paleolithic past To our cave-dwelling, hunter-gatherer ancestors, who were somehow protected against depression, most likely by their highly social, active, outdoorsy lives, Ilardi theorizes.

We've gotten off topic but now the imagine the life of a caveman, without cars, large corporations, and electricity. Our only pollution will be our bodily gas! I believe "living like a caveman" is a perfectly and only viable solution to inhibit this planet without killing it. Maybe we'll even be happier without our latest gadgets. Look at Fred, Wilma, Barney and oh so sexy Betty, from the Flintstones, they were all so happy. So I want to leave you with a hypothetical question. If we could ALL go back to living like cavemen/women, would you want to?
No school, work, or bills, and if your lucky, maybe you'll find a girl like Wilma or Betty.
