Sustainability means resolving the conflict between two competing goals:
the sustenance of human life and the integrity of nature.
Why two competing goals? Living beyond our ecological
means will lead to the destruction of humanity's only home.
Having insufficient natural resources, and living in
unsatisfactory and inequitable ways will cause
destructive conflict and degrade our social fabric.
In a sense, we putting a new spin on the old nature
vs. nurture question. How can we get nurture without
destroying its ultimate source, nature?
Redefining Progress
Sustainable development involves the simultaneous
pursuit of economic prosperity, environmental
quality and social equity. Companies aiming for
sustainability need to perform not against a
single, financial bottom line but against this
triple bottom line.
The World Business Council for Sustainable Development
Improving the quality of life while living within
the carrying capacity of supporting ecosystems.

GOVERNMENT DEPARTMENTS & AGENCIES
Each generation is entitled to the interest on
the natural capital, but the principal should
be handed on unimpaired.
Canada's Commission on Conservation (in 1915)
Sustainable development means implementing a process that integrates
environmental, economic and social considerations into
decision making. This reinforces the World
Commission on Environment and Development's
conclusion that development should be sustainable
for the benefit of current and future generations.
Environment Canada
Development which ensures that the utilization of resources
and the environment today does not damage prospects for
their use by future generations.
Canada's National Task Force on Environment and Economy
Living on the earth's income rather than eroding its capital.
It means keeping the consumption of renewable natural
resources within the limits of their replenishment.
It means handing down to successive generations not
only man-made wealth, but also natural wealth,
such as clean and adequate water supplies, good
arable land, a wealth of wildlife, and ample forests.
