"The fate of the European bison provides an example of the way in which a species may be brought to the brink of extinction in a very short time, and then saved only through great efforts, " says Dr. Zbigniew Krasinski of Poland's Bialowieza National Park.
Recent research suggests that there was, in fact, no impact in the North Sea at all, but the Ukrainian site does appear to be the result of a genuine collision that took place at the time of the dinosaur extinction and could therefore be connected with Shiva.
Privately-funded efforts to save this regal bird from extinction had been underway for some time at that point, and the federal government began its own efforts in 1966 with the passage of the Endangered Species Preservation Act, the precursor to the more comprehensive Endangered Species Act (ESA) of 1973.
