Throughout the past month, nearly 700 Magellanic penguins were found dead on the Brazilian coastline. To make matters even worse, most of them were mere youngsters born just a year ago.
As was to be expected, marine biologists first thought these deaths were caused by some human-related activity that somehow interfered with the natural balance of the marine ecosystems in this part of the world.
However, try as they might, they couldn't possibly put the blame on anybody, be it local community or industrial company.
Thus, they had no choice but to conclude that everything happened because of natural causes. Interestingly enough, this also pretty much got them nowhere, as they still cannot say for sure how it was that the animals got sick.
Apparently, similar incidents have occurred in previous years as well, but a reasonable explanation is yet to be found by researchers.
