Summary

More than half of the world's population already lives in cities, and another 2.5 billion people are projected to move to urban areas by 2050. The way we build new cities will be at the heart of so much that matters, from climate change to economic vitality to our very well-being and sense of connectedness. Peter Calthorpe is already at work planning the cities of the future and advocating for community design that's focused on human interaction. He shares seven universal principles for solving sprawl and building smarter, more sustainable cities.

0:00.0	This TED Talk features urban designer Peter Kalthorpe, recorded live at TED 2017.
0:07.0	So let me add to the complexity of the situation we find ourselves in.
0:13.0	At the same time that we're solving for climate change,
0:17.0	we're going to be building cities for 3 billion people.
0:22.4	That's a doubling of the urban environment.
0:25.8	If we don't get that right, I'm not sure all the climate solutions in the world will save mankind.

1:23.6	or many people think of, as low-density development
1:26.6	out at the periphery of the
1:28.2	metropolitan area. Actually, I think that sprawl can happen anywhere at any density. The key
1:35.9	attribute is that it isolates people. It segregates people into economic enclaves and land use
1:43.8	enclaves. It separates them from nature.
