This is a really good article and I think this problem is absolutely ubiquitous. Mapped flood zones and also modeled flood risk does not align accurately with actual flooding experience, including impacts across heterogenous built environment.

Lower fertility rates worry economists: fewer workers, slower innovation, and ageing societies. But researchers say resilience matters more than reversal. A smaller population can even bring environmental benefits.

Like other factory farms, farmed fish or “aquaculture” spreads disease & drives climate change — from the destruction of mangrove ecosystems that sequester carbon to on-farm emissions, fossil fuels & the undermining of local food sovereignty.
