So, if salt is so important, how did they get it from one place to another before we had trains? One of the key details of Phase I of the Four Freedoms movement is public transportation, as important back in time as today, right?
1.) Why is salt important, biologically?
2.) Why was salt traded from place to place?
3.) Share your thoughts on whether salt supplies could have influenced wars.
4.) Write a book, story, blog post or tweet that uses those thoughts, and please tell us about it! If you write a book, once it is published please consider donating a copy to your local public library.
