Yes. Man will never stop wanting, sooner or later the earth will have nothing to give. Nuclear means - crafts- space - planets - mining.
On another note i just view something funny on the news, Some bright spark gave the all clear to send 1.8billion dollars - in cash! Loaded in pellets and was suppose to be shipped of to iraq - yet it went missing
they have no idea what has happened to the money! Somebody out their is now looking at some islands to buy for retirement.
Ignore the above not meant to hijack but hey thats out of it!
