Preparing for resource
constraints is in overwhelming
self-interest of cities and
countries. (much more so than for
individuals or companies…)

The Ecological Footprint and
biocapacity (per capita) of three
countries from 1961-2005. A country
runs
an
Biocapacity per
person
ecological deficit
if its Footprint exceeds what its
ecosystems can renew. The deficit is
made up through net-imports, net-carbon
emissions to the global atmosphere, or
local resource degradation.

Summary
• The planet has limits. Do you know
how much biocapacity you have?
and how much you use?
• Blindness costs lives & opportunities.
• Economic stability and competitiveness
depends on managing eco-deficits
