Is Nature Exposure worth prioritizing?

A systematic review and meta-analysis of cohort studies in The Lancet Planetary Health found greater green space exposure is associated with lower mortality, a finding reinforced by an independent systematic review of residential green space and by a dedicated meta-analysis in older adults finding lower mortality and cardiovascular risk. Weighing that against the numbers, Nature Exposure is reasonable to include, though not a top priority — the evidence is rated strong (74/100), but its estimated effect on longevity is modest (45/100).
