Natural Resources and Sustainability What does the word “sustainability” mean to
you?
![Page 7: Bay Area Earth Science Institute](https://reader035.vdocument.in/reader035/viewer/2022062518/56814c26550346895db92d0d/html5/thumbnails/7.jpg)
A common definition
The World Commission on
Environment and Development (the
Brundtland Commission) in its
report Our Common Future (1987):
“Sustainable development is development that meets theneeds of the present without compromising the ability of future generations to meet their own needs.”

Sustainability: More than the environment
Three “dimensions” of sustainability: Environment Economy Society
“People, Planet, and Profit” Includes societal and intergenerational equity

A Better Model?
Concentric circles: The economy exists within society. The economy and society exist within the environment.

Sustainability as a Process We know what unsustainable practices look
like, but we’re learning about a sustainable future as we go along
Education for sustainability Interdisciplinary Skills:
Systems thinkingCritical thinkingProblem solving

What do people NEED?
Think-pair-share:
What do people need to assure their well-being?

What Do People NEED?
Food Water Air Shelter
Can you think of others?
Meeting these needs requires Earth’s resources

The Lorax Using Dr. Suess’s The Lorax
to teach students about sustainable development The Lorax was written in 1971 and is considered a metaphor for unsustainable use of natural
resources.

The Lorax: short synopsis A young boy goes to meet a ruined industrialist in a treeless
wasteland and hear his tale of what happened to him. His tragic story is about how he began a thriving business
with a useless fashion product (the Thneed) derived from the trees of a forest.
As his business booms, the forest and its inhabitants suffer as he wantonly clearcuts without regard to the warnings of the wise old Lorax about the dire consequences of his greed.
The lovable Lorax, who speaks for the trees, tries to save his forest from industry (and the greedy Once-ler), but he isn't able to.

Do you really need a thneed? Can you think of some real examples of a
“thneed” (i.e., a product people want, but don’t need)?

The “real cost” of food/products
Materials/energy to extract, produce, transpose, dispose of, etc. Examples (handouts)
What resources are needed to make a burger, fries, and Coke?

Ecological Footprint A tool for measuring humankind’simpact on nature
Estimates the area of land and ocean required to support consumption of food, goods, services, housing, and energy and to assimilate wastes.
Expressed in "global hectares" (gha) or "global acres" (ga) 1 Hectare = 2.5 acres
Categories: carbon (home energy use and transportation), food, housing, and goods and services.

Overshoot (ecological deficit): Living Beyond Our Means
Taking more resources than Earth can provide, or using them faster than they regenerate
Putting more wastes into the ecosystem than the earth can absorb.
Ecological productive land available for each person on Earth: 1.89 hectares (4.5 acres)
Current average usage: ~ 2.2 hectares (5.5 acres)(~ 20% overshoot).
