What will happen if one day we would get in contact with extraterrestrial intelligent life and societies. Are they developed? Are they already gone? Or will they emerge? Do they destroy their living conditions? Or have they already learned how to live right on their planet? In any case, we should be prepared, for the best and for the worst. In such a fictional encounter, our planet should be in its best form, with healthy ecosystems, rich biodiversity, moderate global temperatures, peaceful nations, developed human societies, prospering sustainable economies, within a global democracy system, etc. Maybe one day in the future there would be a “Planet Competition - Universe Sustainable Development Challenge”, where all existing intelligent civilizations of the Universe would take part. The respective planet-inhabitants who care best for their home-planet would win the competition, honored with the Universe-Sustainability-Trophy.
