Stephan:   This is part of how a society fosters wellbeing. Think about how relatively inexpensive planting the trees was, and how impressive its affirmative social effect has been. This is the kind of thinking we need from Congress, instead of the culture war we now have.

Money may not grow from trees, but something even better does.

In a new study led by the US Department of Agriculture (USDA) Forest Service, researchers found that each tree planted in a community was associated with significant reductions in non-accidental and cardiovascular mortality among humans living nearby.

On top of that, the study’s authors conclude the yearly economic benefits of planting trees dramatically exceed the cost of maintaining them, by a factor of more than 1,000.

Previous studies have linked exposure to nature with an array of human health benefits. Access to nature is a major factor for mental health, and that doesn’t necessarily require the greenery to be primeval wilderness. Research shows urban forests and street trees can offer comparable benefits.

Several longitudinal studies have shown that exposure to more vegetation is associated with lower non-accidental mortality, the authors of the new study note, and some have also linked exposure to greenery with reduced cardiovascular and respiratory mortality.

“However, most studies use satellite imaging to estimate the vegetation index, which does not distinguish different types of vegetation and cannot be directly translated into […]
