Civilians on the British home front were affected by World War 1 in several ways:
1) Food rationing was introduced in 1917 and became compulsory in 1918 to address food shortages caused by German U-boats sinking British merchant ships carrying supplies.
2) Conscription was introduced in 1916, requiring all men aged 18-40 to register for potential military service.
3) Censorship of soldiers' letters and limitation of news about casualties was implemented to maintain public morale and support for the war effort.
