Why Food Storage?

I was thinking about food storage lately, and I wondered what other people were doing.  I came across this video with a man telling us about what he's done in regards to food storage.  I really liked it because he talked about how and why he's started storing food.  I like his setup, and how he mentions random things that people don't necessarily think about.  He even talks about bartering!  Check it out, and start thinking about what you can do!
