I live in a country where a staggering proportion of the population live in just a handful of cities. And because of how inefficient and sometimes unpleasant our crowded cities are, especially my hometown of Sydney, I often wonder how countries facing rapid urbanisation could handle the problem better than we have. Is there a better way to plan cities so we don't spend so much of our lives staring at an endless sea of traffic, or jammed onto trains and buses like Sardines? This TED talk by Kent Larson, who has been advising the Chinese on just this issue, is a great watch for those wondering how more efficient cities (and our lives) could be in the future. I for one can't wait to live in an apartment with “infills” that can adjust the space to my current needs.
