We do something either intentionally or by accident and as a consequence of that action a whole load of unintended consequences follow.
Those consequences can be good or they can be bad. If they are bad and we notice them we can take corrective action.
But too often, we either do not notice the consequences of our actions or if we do, we do not attribute them to our original action.
Things change and we have no real idea why and the last thing that we do is to put it down to our own actions.
This little video about wolves in Yellowstone Park is a wonderful example of this in action The last wolf was killed in Yellowstone National Park in 1926 and they were not reintroduced until 1995.
Seems the impact has been amazing. Would you ever expect less than 100 wolves to actually have an affect on the course of the rivers in Yellowstone Park. Take a look at this video and see why! How wolves change rivers or read about it here in the History of wolves in Yellowstone.
What else do we do or decide not to do in this world but have no idea of the real consequences - many of them long them where the connection between cause and effect is lost?
