How did each of the following military, economic, or political issues apply to world war i?

natural shipping:

trench warfare:

u-boats:

Natural shipping: Germany had a policy of unrestricted attacks on shipping vessels thought to be carrying troops, supplies or weapons for the Allies. This policy was suspended after vigorous protests by the USA because it violated American neutrality. In 1917 Germany reactivated this policy and the US finally decided to declare war on Germany in April of the same year.

Trench warfare: Trench warfare was devastating for both belligerents. The cold, the chemical weapons, the bombs, the fighting the diseases, the malnutrition, the unsanitary conditions killed millions of young soldiers. Due to the devastating loses, this generation of young victims and survivors came to be known as the Lost Generation.

U-Boats: Germany greatly developed this method of warfare and sank hundreds of shipping and military ships from Allied and neutral nations.

Liberty Bonds: these were debt securities that were sold to the general population to finance the war effort. Billions of dollars were collected thanks to the liberty bonds. There were cases of malfeasance by stock brokers in Wall Street.

explanation:

native american contribution: the patriots from britain learn how to hunt, fish, and introduce diversity within cultures.

african americans: indirectly introduced the idea of diversity to americans. africans coming to america because of slavery taught white americans that people come from different backgrounds and colors. it also built america's economic stability for a great period of time. 

women: make america what it is today. there are some societies that are in the world currently that do not give women the same right we give women here in the united states. because women have rights here in the united states, other countries' citizens strive to come to america, especially women, since they have equal rights in the united states. this is important because america is seen and desired by many in the world. 

children: children are our future. we learn from our elders and carry out things the same or differently learning from america's history. we continue tradition and change tradition if it is needed.
