Did you watch the Youtube video I posted yesterday?
Here's a couple of notes I joted down from it:
Civilization is defined by cities.
Required importation of resources means your civilization will never be sustainable and will always have to be violent.
If you require something to live and maintain your civilization and you normally can get it by trade, but now the only people who have it won't trade with you ... then you have to take it. Look to oil in the Middle East, for example.
Industrial civilization requires violence. It is built on violence. It is the end product of violence.
This is just so in-your-face true that I can't get around it. I believe, as Christians, we now have our response to the question of reconciling Christian beliefs with an industrial world.
