The planet's biggest problems have to do with sustainability, environmental decline, global poverty, disease, conflict and so forth. Really, they're all interconnected - it's one big problem, which is that the way we're doing things can't go on. Alex Steffen bigconflictdecline share on social
Cities generate most of the global economy, and most of its energy use, resource demands and climate emissions. How we build cities over the next decades will largely determine whether we can deliver a bright green future. Alex Steffen brightbuildcity share on social
For carbon-neutral cities, there are things worth talking about in how our consumption patterns can change - sharing goods, etc. - but those are a fraction of the impacts of transportation and building energy use. If we need to choose priority actions, the most important things are to densify, provide transit, and green the buildings. Alex Steffen actionbuildbuilding share on social

Cities are responsible for the vast majority of the creation of the economy. They're also places into which we pour the vast majority of resources, the vast majority of energy and the places where a huge percentage of the decisions about how systems are built and how products designed, etc., happen.

It's not that hard to imagine the natural world recovering it's health in our absence: it's more difficult, and more necessary, to imagine it recovering its health in our presence. Alex Steffen absencedifficulthard Change image and share on social
