Sustainability seems to be the new century’s catchword for the leading edge of responsible environmentalism and economics. I came across this site/blog http://www.worldchanging.com/ with a focus on products, shelter, politics and more. They have an email newsletter, and just published a book.
They pay special attention to “tools, ideas and models that may have been overlooked in the mass media and make a point of showing ways in which seemingly unconnected resources link together to form a toolkit for changing the world.” Managing your ecological footprint isn’t an all-or-nothing proposition. It starts with incremental change(s).
Looks like something to keep an eye on, I’ve bookmarked it.
