There is actually a documentary called Collapse. It really connects the dots with how The entire global system is headed for collapse, due to the extraordinary dependency on petroleum for just about every product on the market. Nothing moves without that petroleum. Without it (or a replacement) the entire system grinds to a halt.
Understand this and you can begin to understand why so many wars have been fought over oil, it is the juice that runs these systems. Without oil, there is no capitalism. And, the oil is running out. The entire system was built on a limited resource, a resource that it took the earth 300 million years to create. We have nearly exhausted it in about a hundred years…something isn’t right about that.
These ideas are good ones. Food, shelter and water are going to be more critical than ever. Already the food is so damaged by mass production. This is why everyone wants organic.
