This sobering video by Isao Hashimoto speaks for itself. You'll need about 15 minutes to watch the whole thing, but if you want a reminder of what the pace of testing in the nuclear age has been, this is well worth it. [youtube=http://www.youtube.com/watch?v=I9lquok4Pdk&hl=en_US&fs=1]
The reminder that more than 1,000 nuclear explosion took place in the American Southwest almost leaves you wondering how the entire region isn't an atomic wasteland, doesn't it?
The official page for this video on the site for the Preparatory Commission of the Comprehensive Nuclear Test Ban Treaty Organization has more information about the artist.
(As the page notes, the video does not show two nuclear tests that occurred after 1998, both by North Korea, in October 2006 and May 2009.)
