I remember my surprise, when I first read (possibly it was in one of the Tarzan books I read as a child) that the most dangerous creature on earth is Man, Homo Sapiens.
As a member of the human race, I felt personally insulted.
When I read justifications to this claim, I felt there may be some point to this claim.
Want to read more about it? just google... (or click here).
But that is NOT the subject of this post...
You see, part of the claims talk about how humans invent weapons that are much worse than what's needs, and use them much more than what is needed.
Other times it'll be about how "unintentionally" we (humans) do something with "unintended" harsh results.
I'd like to talk about one of these tools.
