William McDonough TED Talk
Here is the 22 minute TED talk (Technology, Engineering and Design) by William McDonough, a developer of the Cradle-to-Cradle concept. It is well worth watching, but you will get more out of it if pay attention.
HOMEWORK for WEEKEND (1/30/14 to 2/3/14)
Find out where aluminum comes from. Get the details, not just a word or sentence. A diagram would be nice...
Story of Stuff
We may watch this in class if time, but it is interesting enough to watch twice. This traces a generic life cycle of some common products and discusses (among other things) the idea of "shifting" environmental damage intead of preventing it. It is very accessible (not boring) and provides a lot to think about and discuss. (~21 minutes long)
WASTE = FOOD
Here is a link to the video we watched in class. If you were absent, make sure you watch the part(s) you missed.
How Paper is Made (In class, 2/11/14)
Paper Cuts: How paper is made
How a T-shirt is Made (In class, 2/14/14)
COTTON: Planet Money Makes A T-Shirt
Part I: Material Acquisition and Processing
Part II: Manufacturing
HOMEWORK OVER BREAK: (2/14/14 to 2/24/14)
DUE WHEN WE GET BACK:
Analysis of at least 4 components of your item
to the degree we have practiced in class.
REFERENCES FOR EVERYTHING!!!
Examples from Class on 2/14/24
Cotton Growing Impacts/Inputs
"Anti-poison chemical" GMO (Genetically modified organism)
- More chemicals are used!
- Potential damage to water supply
- contaminate soil
- kills things across the board - include butterflies!
Energy is used for the machines to pick the cotton
- Comes from fossil fuels
- Damage land and water getting them out
- Damage air being used/air pollution
- Greenhouse gases/global climate change
Water is required to grow cotton
- If rain, possible no negatives
If irrigation using groundwater
- Salinity of soil possible
- Ground water depletion possible
- Huge fields of cotton reduce biodiversity and take over habitat
Cotton Processing and Manufacturing Impacts/Inputs
- Water is used to wash the cotton
- Degrades water quality; water must be treated
- Soap used may or may not be biodegradable
- Fuel/Energy source for the machines
- Probably from fossil fuels
- Land degradation
- Air/atmosphere pollution/climate change
- Cotton is dyed
- Dye may or may not be biodegradable
- Extra cotton/scrap cotton might be landfilled
- Boats use fossil fuels
- See above
- Boats might sink and/or pollute
Coggle It Mapping Website (to make diagrams like the one we worked with in class):
If you want to research further (the next steps of the life cycle: packaging, transport, use, end of life...) go for it! When we return we will set a final due date and exact minimum requirements.
Have a good week!
