An Acknowledgement

All humans have basic physical needs: air, water, food, clothing, and shelter. These must be supplied by resources on the planet.

Human population is increasing, but the planet remains the same size. While human needs are distributed evenly across the population, the resources supporting wellbeing are not.

Humans are now the stewards of all living things. With 7.8 billion humans touching every ecosystem directly or indirectly, we will determine the fate of all plants and animals, including ourselves.

As our economy has grown, we have degraded our natural environment.

In the process of powering civilization, we polluted the air, acidified the oceans, tainted freshwater, eroded topsoil, hunted large mammals into marginality, and otherwise diminished biodiversity. These actions have resulted in shifting weather patterns, extended hot seasons, more frequent hurricanes and tornadoes, coastal flooding, and increasing intensity of wildfires.

The Clarion Call

All humans also have basic social needs: a desire to flourish, to commune with others, self-expression, and meaningful existence.

Our generation is charged with crafting a way of life to responsibly accommodate a growing population while allowing humans to pursue their full potential. We need to do so in a way that ensures humans and other species can thrive for millennia to come.

Cities are the best platform for delivering human wellbeing and environmental resiliency at scale. Cities efficiently create and deliver housing, jobs, transportation, community, food, electricity, water, and sanitation. All other ways of human settlement require more resources and serve fewer people.

However, cities are not yet efficient enough to support our modern lifestyle without having an adverse impact on the planet.

We need an audacious reimagining of what cities can become.

Our Manifesto

Build walkable cities (again). Walkable neighborhoods minimize energy use from housing and transportation, preserve natural land, and encourage healthier lifestyles. This urban form generates tightknit communities, spontaneous social interactions, and access to diverse cultural experiences. Also, walking a city is fun!

Build beautiful cities.

Humans want to be inspired. People will only opt into a more resource-efficient lifestyle if cities are the most attractive option.

Build natural cities.

Blending buildings with nature promotes local species, is climate-cooling, and makes dense city living pleasant.

Build affordable cities. If we build walkable, beautiful, natural, and energy efficient cities that are only accessible to a small slice of the population, we have not solved the problem.

We have conviction in the value of cities, but we do not know all the solutions. We are humbled to work on crafting a lifestyle befitting the 21st century and commit to a lifelong journey of learning.
