#161--"There are three things which build and maintain civilization throughout time: pure air, pure water, and pure food. And as an eternal truth I say unto you, that there are three things which bring the end of civilization, even the mightiest that have ever been and shall ever be, from the beginningless beginning to the endless end of all time: impure air, impure water, and impure food." ~ Zenda Avesta, 3,000 years ago.
