The old saying goes something like, "Possessions don't make you happy." A more dire version is, "What you own, ends up owning you."

Are these old adages true or just the empty words of ancient party-poopers challenging you not to buy an iPhone 11? According to a new study of 968 young adults by the University of Arizona, being materialistic only brings us misery.

The study examined how engaging in pro-environmental behaviors affects the well-being of millenials. The study found two ways in which they modify their behaviors to help the environment: they either reduce what they consume or purchase green items.
