Freegans :

Quite sometime back I had read about this girl (in US), who would search in garbage bins for food and use it. Not that she was poor but that she was a part of community called Freegans. I had lost the link for it, but then today again it popped up in one of the feeds.  Freegans are community where people believe in using the minimum resources required for living and conserving and reusing stuff.

An excerpt here 

"It's not a few bad products or a few egregious companies responsible for the social and ecological abuses in our world but rather the entire system we are working in, we begin to realize that, as workers, we are cogs in a machine of violence, death, exploitation, and destruction."

This is so similar to Story of Stuff. 

Sometimes I also wonder, being a hardware engineer about all the hi-fi tech stuff we keep making. Increasing speeds from Kbps, to Mbps to Gbps and so on. If all this is worth it?
