Foundational Texts for Sustainability
I thought it would be interesting to look into the relative influence over time of several of the most important early texts for Sustainability. Justifying my selection would be a whole post in and of itself so lets just go with it.1)Also, I don't actually have valid justifications for choosing these works but I think for pre-1990 these are widely recognized as some of the most important. I choose A Sand County Almanac (1949), Silent Spring (1962), Limits to Growth (1972), Small is Beautiful (1973) and Our Common Future (1987).2)Somewhat to my own embarrassment I have actually only read Silent Spring and Sand County Almanac, the others I know by reputation and selected passages only. Now lets get to the fun, graphics!
