Atlantis
To this day we still aren’t sure if Atlantis existed at all! Some believe that the sunken city is off the shore of Greece, while others claim that it is near Japan. We don’t know what to believe since so many discoveries from the underwater city have been debunked.
Iceless Antarctica
Can you imagine an Antarctica without ice? The white-colored continent that we know today was actually once depicted on a map without any snow or ice at all. The man who created the map was Ottoman admiral and cartographer, Piri Reis. Reis compiled his map in 1513. What really surprises historians and modern-day cartographers is that the continent was only supposedly discovered in 1818. If that wasn’t enough, the map seems to show a bridge which connected South America and Antarctica. Perhaps environmental education wasn’t so strong at that stage.
