Existing states are responsible for the destruction of indigenous populations and their societies, and thereby have an obligation to help reverse the effects of their actions  The Indian Removal Act of 18301, the 1871 Indian Appropriations Act, and the 1887 General Allotment Act are just a few examples of legislation used to destroy Native American communities in the US2. Settlers in Australia are similarly responsible for a multitude of massacres3, as well as several decades of forced separation of aboriginal children from their parents in an effort to "Christianize" them4. While the current citizens of Canada, the US, and Australia are not guilty of the crimes of their predecessors, they nevertheless reap the benefits of those atrocities while today's indigenous populations still suffer from the lasting impact of oppression. When chemical companies make huge profits at the expense of damaging the surrounding community's environment, those companies are expected to pay reparations. A government that destroys an indigenous culture must similarly work to reverse their destruction.  1 Indian Treaty and Removal Act of 1830, U.S. Department of State. 2 Preamble to the Trail of Broken Treaties 20-Point Position Paper: An Indian Manifesto.
