Limits to our Civilization?

There is an interesting article at the always interesting site Automatic Earth, is there a limit to growth? being the theme.http://theautomaticearth.org/Earth/the-limits-to-mankind.html

My view on this subject is to side with the scientist and say that nothing lasts forever and that our society will follow every other great civilization known to have existed and eventually collapse.
You only have to look back in history to see that no civilization has lasted forever, each meeting it's demise when circumstances change and the civilizations' capacity to adapt is tested to the limit.
Our current civilization based upon constant growth and consumerism within the capitalist system is under threat because the oil, literally and figuratively, that lubes our civilization is finite in supply.
And as scientists never tire of telling us, nothing lasts forever.
So quit fretting and enjoy it while it lasts for however long it lasts....
