learning ecological design

Quotes and statistics are from the booklet Okala; developed by Steve Belletire, IDAA, Louise St. Pierre, IDSA, and Philip White, IDSA for the Ecodesign Section of the Industrial Designers Society of America © 2007

Okala oqala from the hopi language meaning life sustaining energy l.jpg
Okala: (oqala)from the Hopi language, meaning life sustaining energy

  • The energy used to create, develop, manufacture and use products can sustain life on this planet, rather than deplete it.

  • Implies a forward and optimistic view

  • Designers who persistently seek out ecological design work will have the greatest opportunity to make a meaningful difference.

Some sobering statistics l.jpg
Some Sobering Statistics

  • The natural environment has always been affected by the presence of human beings

  • Since the beginning of the Industrial Age (approximately 1750) the environmental impact of human activity has increased exponentially

  • The consumer driven economy we live in now has only made that impact worse

  • Statistics that reflect that include:

Global temperatures l.jpg
Global Temperatures

  • The global temperature averaged 57.4 degrees F in 1965 and 58.6 degrees in 2006. A raise of 8 degrees F would turn all of the earth’s land surface into desert scrub except for the most Northern and most Southern latitudes.

Melting ice caps l.jpg
Melting Ice Caps

  • Ice on the North and South poles and Greenland is melting at an alarming rate; if half of Greenland’s ice melts, the oceans worldwide could raise 20 feet.

Forests l.jpg

  • Nearly half of the world’s old growth forests are gone.

Human population l.jpg
Human Population

  • Human population will grow from 6.1 billion to 9 billion by 2050.

  • Most of that growth will occur in increasingly industrialized countries such as China and India.

Fish stocks l.jpg
Fish Stocks

  • The 1950-1997 oceanic fish harvest grew from 19 million to 95 million tons, resulting in major declines of many species.

Declining bio diversity l.jpg
Declining Bio-Diversity

  • 11% of all birds, 25% of all mammals and 34% of all fish species are on endangered species lists. 50 % of all tropical plant species are at risk of extinction.

  • The cause is destruction of habitats from human interference, pollution and climate change.

Farming the environment l.jpg
Farming & the Environment

  • Arable cropland demand is converting forests to land used for non-biologically diverse crop species.

Time for a thought experiment l.jpg
Time for a Thought Experiment

  • What would the world be like without humans?

  • How long would it take to get rid of all signs that we had been here?

Plan the product for optimized end of life l.jpg
Plan the Product for Optimized End-of-Life

  • Integrate methods for product collection

  • Provide for ease of disassembly

  • Provide for recycling or down-cycling

  • Design reuse, or “next life of product”

  • Provide for reuse of components

  • Provide ability to biodegrade

  • Provide for safe disposal

Final thoughts l.jpg
Final Thoughts

  • Keeping an ecological perspective should be important to a product designer

  • Reduce, reuse, recycle are the “three R’s” of product design

  • The Okala approach to product design is the way to succeed as a designer

  • Educators of design have an obligation to encourage the Okala approach in the work of their students
