>So the #1 thing an American can do to fight climate change is be "pro-city". Move there. I love the idea of higher-density living, the problem is that it's simply unaffordable for a large part of the population. They can only afford houses with yards and several feet of air-gap, as you put it. How do you propose to fix this? For example, look at Japan. In Tokyo, you can rent a small (very small) efficiency apartment for perhaps $500, according to what I hear on YouTube. A larger one big enough for a couple might be $900 or $1000. Such a place will be clean, safe, and just a few minutes' walk from the subway. Now look at NYC: there's no possible way you'll find something to rent at that price in a place that's at all safe. So telling people to "move there" is really rather asinine; are you going to pay me $1500/month so I can afford a livable apartment in Manhattan? (I'll make up the other $1000 on my own, your $1500 is a subsidy) As long as the property owners in a municipality have all the power over building and density, we're going to have this problem.
