I saw an ad on tv for a video called ' end of america 1 . com' (website). It is a sales pitch for farmland. "The sky is falling!!"
It had accurate information in there but yes, it was basically a sales pitch. Probably tells you to invest in water at the end for only $99.95.
Buying land might not be a bad idea, and certainly water is a commodity that has been taken for granted by people in the First World for too long, but I doubt you would need to pay someone to tell you that.
