48. Guaira Falls, Paraguay and Brazil
Guaria Falls was an incredible series of enormous waterfalls along the Paraná River that ran along the border of Paraguay and Brazil. It was in its height waterfalls with some of the greatest flow rates on Earth. But, of course, no such beauty can be left untarnished.

In 1982, the Seven Falls ceased to exist when the Itaipu Dam reservoir was brought into being. It was a cold, chilly symbol of so-called industriousness that attracted many to watch and mourn its end. Tourists and indigenous folk alike gathered on the day the dam was put in place.
