CHATTANOOGA, Tennessee -(WDEF) Hundreds of people came out to the Sustainable Preparedness Expo in Chattanooga this weekend to learn how to survive should they ever have to go weeks or even months without power or available food and clean water as a result of a disaster.
Vendors displayed alternative ways of producing and preserving food as well as purifying water.
A discussion on how to create fuel and harness alternative forms of energy should the country suffer from a massive electronic magnetic pulse attack also came up during a public seminar.
"If anything like that happens and it is very possible,the entire country could go down and we could have a total country grid down. It could be devastating and so what do you do if more than three weeks or fours weeks go by and you're not prepared," said sustainable energy expert Craig Meissner.
Meissner went to say many people don't bother using sustainable forms of energy and food production because it's not convenient for their lifestyle.
