That sinking feeling

This makes sense in retrospect, but I would not have predicted it: fish farms set up near the Yellow River delta are contributing to a faster-than-average sea rise in the area. The fish farms are using well water for their operations, at such a clip that it's lowering the water table. And the soft soils of river deltas will subside, or settle under their own weight, without that water content.  The article mentions a related phenomenon in Houston in the 1920's due to oil extraction.
