Hello,
As the war approached, it got worse for farmer... The United States responded. First, the U.S. decided to send its destroyers to hunt the U-Boats and keep shipping lanes open. Hormel had introduced the canned meat product Spam in the 1930s. It proved to be an ideal combat ration because it could be shipped easily and wouldn't spoil for long periods of time. Soldiers could fight only as long as they had food to fuel their bodies. So, farmers were exhorted to produce even more.
Ordinary colonists were able to learn more and know more skills to be able to do more things that they cannot do. For example, cook, chop wood, gather food, etc
hope this helps
