Having grown up in the shadow of the Bomb and having provided supportive care to post-Cold War generations of children and their parents (both in crisis), I have seen a lot of distrust and instability in people--individually and in communities. I have seen how the shadow of impending doom can rewrite a way that people live.
This distrust and instability is not a personal issue. It is a sign and symptom of having lived in a time when the imagination can harbor not simply notions of tribal decay and destruction, but the decay and destruction of all tribes, in all places, and throughout all future time. We can wipe out everything that exists within the realm of our planet--in an instant. This changes who people are. This changes how people grow and develop.
The current earth crisis is large. It looms overhead and in our homes. It is more visible and prevalent than the crisis of the Bomb. Everything we pick up and discard is a reminder that we have a problem. In many ways this crisis is more severe than the Bomb. In this crisis everyone has a button they can push to bring destruction. We have more madmen to worry about. Everyone. Everyone has an impact on global ecologic and climate issues.
Here are poets' songs on the beauty of the earth, lest we forget.
