Intersting site. I had to look over it a couple of times to see if I was understanding it correctly. From what I see there, they state that food / drink for one person to live for one year is $300. If that is the case, then I must be doing something very wrong!!! My grocery-bill for one person for one month is about that much!
One thing I noticed was that they are pushing Berkey filters. There are a couple of Canadian companies that I have contacted about putting together a water-filtration system to work with my camping trailer..
