And when they are, cities can perform the essential service of 21st century urbanism: creating regenerative buildings and landscapes that produce more good for more people
rather than places that are merely less bad: More clean energy, more fresh water, more fertile
soil, more food, more productivity, more biodiversity — more
health and well - being for all.
Organic systems, by contrast, restore
soil health, foster biodiversity, and recycle organic matter
rather than lading the land with synthetic chemicals.
