Most of the noise in cities does come from cars. You're right that cities will never be <35 dBA, but most rural areas are not usually that quiet either. For example, even slight wind will cause ambient noise in wilderness to 40-60 d

Earth science PhD here - you're pretty much right, but Atlantic oceans can still be bad. Most earthquakes are caused by tectonic plate motion. The biggest earthquakes (>M9, e.g. Japan 2011) occur at subduction zones where an oceanic

Very good point about farming and productivity. I believe US manufacturing didn't decline in output either, just increased productivity and declined in workers. Although essentially all the growth in new manufacturing went overseas I b

I've seen other strong studies showing that government cost per-capita is _much_ high for suburban and rural areas. Intuitively this makes sense when considering infrastructure - more people use a road in a city than in a suburb, and v

I think we agree on most practical aspects of this situation. We both agree that this situation of expensive grid hookups in rural areas is simple economics. We both agree to make it affordable would require a subsidy. Rural residents seem

I grew up in a very rural, conservative small town and still talk to many people there. They loved the $1500 checks in their accounts. They see rising cost of housing and several have suggested government subsidies for homes or a massive go

I understand your point - farming, mining, and manufacturing are all essential economic activities that have largely shifted overseas post-WWII. This has hollowed the rural economy in US and other western nations while also making goods vas

1.41m by 2100 is the projection for “Grand Isle”, the closest location in the model to New Orleans. Sea level and sea level rise is not uniform worldwide, so local predictions are very important. This is also true for temperature and other

There are 57.5 million square miles of land on Earth, including mountains, deserts, rainforests, national parks, tundra, and Antarctica. There are currently 7.4 billion people. This works out to ~4.9 acres per person of land of any type. Wo

The deficit mainly matters because we have to pay interest on the loans we take out. If the rates are good, it's actually a great investment. If the rates are bad, it hamstrings future growth, because now the budget is spent paying bac

Good answer, but I think you mean Fe, not Pb.

Yes, there is a reason. We've thoroughly explored the periodic table through our studies of nuclear processes (lots of government funding for anything nuclear weapons related). It turns out you can create a ton of elements we don'
