You don't need to start with heritage sites. Start with office buildings that contain people only 8 hours a day, who do nothing but move money around. Most of those building wouldn't be too difficult to make more efficient and cleaner. Then replace the tenements with decent housing - I guarantee, there are no heritage slums, so that'll keep us busy for a while. Then insulate the apartment buildings and homes, put in water reclamation plants and other energy-saving innovations. Then we'll see about the cathedrals and museums.
You're still mass-evicting people; that's not going to be acceptable to very many people. Not to mention impossible; where's the government going to get the money to buy out all the owners?
No, it really doesn't. You just don't like them.
Nobody should have to work or live in a building that they can't leave quickly in case of fire,
What are you even talking about? That isn't a problem with high-rises; that's a problem with *specific* highrises.
or can't reach all floors of during the increasingly frequent power outages,
Power outages are increasingly *less* frequent, not more.
or can't open a window to get fresh air.
I could do without that just fine, thanks. Don't go deciding that the conditions I find perfectly pleasant and acceptable aren't 'human scale'.
Also, low-rise doesn't block the sun from inner cities,
Neither does high-rise unless you're just building a massive wall of them.
and doesn't fall on quite so many people in earthquakes and explosions.
We're perfectly capable of building highrises that don't topple in earthquakes and explosions; don't blame highrises as a whole for corner-cutting designs.
Besides, earthquakes and explosions don't even happen in most urban areas.
Bonus: the foundation is a lot cheaper and there aren't multiple basements in which people can be trapped. Or mugged.
Yes, and you're also wasting a LOT more land; which you may think is a perfectly acceptable tradeoff, but the only reason you think that is because you live in a country with a paltry population density of 3.5 per square kilometer instead of 450+.
Nobody should live so far from their work, services and necessities that they can't get there on foot, wheelchair, roller-skate, or bicycle.
Except by getting rid of highrises you are in fact INCREASING the distance.
But that would be your ideal world. I only mentioned mine.
No, that'd objectively be a more ideal world. It isn't a matter of opinion since there's only so much available land for development. Either you produce compact cities (and that will necessarily involve highrises to some extent); or you sprawl across the face of the earth, destroying even more nature and farmland than we already do.
You are free to add something original to the thread, rather than just criticizing other's ideas.
Don't throw ideas out there if you can't take them being criticized.
