Aren't suburban neighborhoods actually bad for the environment though. Also the lack population density makes it hard to support the infrastructure costs for a large area with fewer people.
It's complicated, so yes because the reasons you state but in a world where significantly fewer people commute it becomes less of an issue and so it's a matter of changing the things we can change.
So yes, wouldn't it be great people lived in denser environments? Oh yeah, but that's not the choice we're making today. The choice we're making is given that lots of people live a 20-60 minute drive from their jobs would we rather they commute into work or work remotely?
The incentive for living in a dense environment is that you get to use common infrastructure for power, water, sewage, health care etc, rather than running your own septic tank and so on.
Even suburbia isn't dense enough to support those things
I’ve lived in both the city and suburbia and suburbia not only had those things, but those things were better in suburbia.
Now eventually you do get into that problem in rural areas or areas that can’t be densely inhabited (like the mountains), but there’s no fundamental reason people can’t live in five-bedroom mansions and have access to services.
septic tanks?? You're talking about rural America. Not suburbs. The only suburbs I've seen with septic tanks were in neighborhoods sitting below the main sewer line. Because shit can't run uphill. Power and water? Do you know a single suburb not connected to the power grid or doesn't have running water? Do you live in the 1800s?
I think the GP's implication is that maintaining these things at low density is unaffordable, although I haven't looked for any figures to see if there's any truth in this.
Fortunately with modern technology, you can run your own composting waste disposal, water from rainwater or aquifer, electricity via solar panels and batteries and the entire package is surprising affordable. That is to say cheaper than in urban 2000 square-foot condo.
That is an incentive for somebody else who likes to tell other people how to live. Not for me. I bought a house in suburbia. My basement is filled with home lab, workshop (wood and 3D printing), indoor garden (wintertime leafy greens and starters for the spring), my partner's art studio in place to store telescopes.
Our yard has rhubarb, asparagus, strawberries, blueberries, blackberries, apple trees. We are re-wilding the lawn to help encourage local insects and birds. I am working on my neighbors to shield their outdoor lights so that nocturnal creatures aren't messed up as much by nighttime lighting.
I figured out once that for me to live comfortably with all of my hobbies/WFH, my partner and her son, I need approximately 2500 ft.² of living/working space. I have lived in shit-a-brick 1500 square-foot urban apartments and it means isolation, earplugs so I can't hear my neighbors, and high blood pressure. I dropped all my hobbies and did nothing but work because the urban space, was for me, the embodiment of depression.
Our neighborhood is dense enough for public infrastructure. Many rooftops around here have solar which is great for distributed power. Sadly my house is circa 1920 with the slate roof and there is no way on cover up that beautiful structure with solar panels.
There are ways to build suburbia they give people room to live where they live. You just need a different perspective.
I have come to terms with the fact that any form of human civilization is not sustainable. We take more then we return to the Gaia ecosystem. At best we can be in balance once human existence returned to a pre-technological, nasty, brutish, and short lifestyle.
Boomers are blamed because of younger generation ignorance. There is an almost a willful lack of understanding of historical events that boomers lived through that shaped their lives and their finances. Looking from a point of older age to younger generations, anyone with half a brain can see the stressors and forces making their lives difficult. Yet we also see the the same forces that shaped boomers doubling down on shaping you. While there are some bright spots of Gen Z pushing back on power structures and winning, those wins are skirmishes because those in power were caught by surprise. In the next conflict, history of social change over the past hundred and 20 years shows that the next conflict will not be won so easily.
From my perspective, the generational you need to take control of politics in your future and stop putting your hands over your eyes and saying you have no control. Get out there, run for office, learn how your constituents live in what's important to them.
Remember, if you do not get elected and take your seat at the table, you will be ignored and nothing will change in your favor. Don't count on others to fight your battles for you.
A dense environment also has a lot of daily destinations within walking distance. That's also very nice when one works from home— either working from home in my Brooklyn apartment, or working from home at my parents' house in a Midwestern streetcar suburb where restaurants/coffeeshops/grocery stores/parks/bars are also a pleasant walk away.
There is plenty of dense housing in prewar sections of Midwestern cities. Not as much as there used to be, unfortunately, but quite a bit, and available very affordably.
