Their 1960's modern arch looks like a glass ceiling...
They should build taller buildings if they want their glamorous gardens to survive.
Coastal cities are turning a bit unstable due to contemporary climate constraints.
E.g. in NYC.
They're building a freaking, pathetic concrete wall cause they're scared of sea level rise, storms and consequences.
They're spending billions of dollars in this thing, but it won't be enough.
A lot people are likely to move inward before 2050. That would be my guess...
So, build taller buildings for more efficient density.
