This was called the Hunger Plan, because the plan called for 20 million people to starve to death. Many would be the Poles, Ukrainians, and Russians who'd previously lived on the land. The rest would be Europe's Jews, who would be worked to death. 6 million Jews were killed by the Nazis, many by starvation, but many through a chillingly planned effort of extermination in death camps. These death camps can be distinguished from concentration camps or labor camps in that their primary purpose was extermination of Jews, Roma people, communists, homosexuals, disabled people, and others that the Nazis deemed unfit. Some historians believe that the Nazis opened the death camps because the Jews weren't dying as fast as the Hunger Plan had intended. This was a sickening plan, but it made a kind of demented sense.
