Peak Prosperity: http://www.peakprosperity.com/
At some point, absorbing more information about the unsustainability of modern society yields diminishing returns. It becomes emotionally draining and thus counterproductive.
Part of this exhaustion results from recognizing our powerlessness within the Status Quo, where independent thinking and structural innovation are intentionally winnowed out as threats to existing institutions and industries.
Another part arises from the burden of knowing that the supposedly permanent Status Quo is far more vulnerable than generally believed. I have described the psychology of knowing what lies ahead in The Burden of Knowing.
