Indigenous people from across the country march in favor of the demarcation of Indigenous lands, and against a law before the Supreme Court that includes a time frame, in Brasilia, Brazil, Wednesday, Aug. 30, 2023. The time frame refers to the stipulation that Indigenous people must have been physically occupying their ancestral lands before Oct. 1988, when Brazil's constitution was signed, in order for their territorial claims to remain valid today.
