Living small(er) in order to minimize carbon footprint makes sense. Green Metropolis by David Owen is a fantastic book that makes the case for Manhattan being a great blueprint for the ideal city of the future -- people living more densely = less energy use individually & less "space" to accumulate stuff and waste. Trash disposal in the city is such a complex problem that residents are literally forced to be economical about their consumption habits. Traditional concepts of homesteading on the plains, whether with large ranch houses or an "eco" house made of straw and mud are not necessarily ecologically friendly when there's imperative need to drive to get to the nearest urban area for work, school, shopping, etc -- these, he argues, are the antithesis of efficiency. Small eco-homes are not just a trend; they are the new era in real estate development. But they need to be built such that they can collectively share infrastructures the same way city residents do. The project I'm working on, applied to YC with (and was rejected from) last batch is built on this idea of more ecological homesteading in order to create better urban planning. Masdar City http://www.masdarcity.ae/en/ http://www.masdarcity.ae/en/ is an interesting prototype for the future of cities. We've schooled our youngins enough for them to know that ecological awareness needs to be a lifestyle. They're surprisingly aware that the world they are inheriting has exponential population growth, limited resources, and that the "industrial revolution" model of economic viability just isn't going to work forever they way it has been working.
