There were also bad consequences, such as the loss of thousands of soldiers and the sinking of several ships, such as Lusitania. For Russia, the prolongation of the war caused serious problems such as the loss of immense territories, the death of thousands of soldiers and the paralysis industry. Food prices have risen and strikes have increased. The economic system has stopped in all sectors. This later caused the Russian Revolution.
