I really appreciated this TEDTalk from Leyla Acaroglu. She dispells common myths about environmental designs by approaching it from a full product life cycle perspective. Assessing impact is not as simple as using "eco-friendly" materials because impact occurs on a systems level, as the by-product of production, transportation, consumption, use, and disposal. Each stage of this life cycle is full opportunities to innovate and transform the impact of a product.
This talk reminded me of a prezi I put together before a GlobeMed rummage sale to explain how used clothing has relevance to global health. This prezi takes a tour through the production stages of a cotton t-shirt, highlighting important questions to ask about how this item is made, used, and disposed of from both an environmental and human rights perspective.
