Dramatic and thought provoking. We do live in blinkered worlds and are rarely aware of the affect we can or do have on others, on life, on the world itself. It is too easy to destroy, mindlessly, yet it takes so little to affect postively: a smile, a thank you, letting someone else go first; even these simple things can bring powerful changes. Your poem reminds me of the film Pay It Forward, based on a real story. A couple of lines are a little awkward, eg:
With a shrug of shoulders and a backward glance
and
The sun blocked all but out
but overall, the rhythm is strong and would make for a powerful performance reading.
