english: The forth pressure is surprise, the notion and the evidence that we need to abandon our old paradigm, that ecosystems behave linearly, predictably, controllably in our -- so to say -- linear systems, and that in fact, surprise is universal, as systems tip over very rapidly, abruptly and often irreversibly.
non_english: Četvrti pritisak je iznenađenje, ideja i dokaz da moramo napustiti naše stare modele u kojima se ekosistemi ponašaju linearno, predvidivo, kontrolisano u našim -- da tako kažemo -- linearnim sistemima i da je zapravo, iznenađenje univerzalno, kako se sistemi menjaju vrlo ubrzano, iznenadno i često puta nepovratno.
