The threat nuclear weapons pose to humanity is severe, and the doomsday clock tracks this threat to humanity. The bulletin of the Atomic scientists created the clock as a means to track the threat of nuclear weapons, but currently the clock tracks climate and bioengineered threats to humanity as well. The clock currently resides at six minutes to midnight (the theoretical time of Doomsday), but has been as close as two minutes and as far away as 17 minutes to midnight.
It is crazy to think that one of the most scientifically advanced discoveries of our time also has the power to bring our species to extinction. As the article stated, a small to medium nuclear warhead is 25 times more powerful than the bomb that fell on Hiroshima. Almost 200,000 people died in the wake of Hiroshima, almost all of whom were civilians.
This highlights the worst attributes of the bomb; it is only used for acts of genocide. I say this since a nuke indiscriminately kills everyone in a concentrated area usually made up of one cultural or ethnic group. Scientist did not design nuclear bombs to settle military disputes scientists designed the bomb to wipe out entire populations.
