“Clean air policies are brain health policies” sounds good, but in practice costly green mandates are more likely to worsen brain health by driving up energy prices, deepening poverty and stripping families of nutrition and care. It’s more probable that poverty, not pollution, drives dementia risk. The surest way to protect brains isn’t by choking off affordable energy — it’s by fueling economic growth that lifts people out of deprivation and builds healthier, longer lives.
