"What does that mean? Does that mean I'm healthier? Or does it mean how we define health from a biology standpoint, that we're missing something?"

BINGO

Civilization is based on the constant importation/production/destruction of natural resources within the confines of a finite planet. This cannot possibly go on forever. Humans are very capable of living outside the confines of civilization, we did it for %90 of our existence on the planet.
But the longer we cling to our "civilized" lifestyle, the less likely we are to leave behind a livable planet when (not if) civilization finally crashes.
