On Feb. 27, hundreds of Indigenous Waorani elders, youth and leaders arrived in the city of Puyo, Ecuador. They left their homes deep in the Amazon rainforest to peacefully march through the streets, hold banners, sing songs and, most importantly, submit documents to the provincial Judicial Council to launch a lawsuit seeking to stop the government from auctioning off their ancestral lands in the Pastaza region to oil companies. An eastern jungle province whose eponymous river is one of the more than 1,000 tributaries that feed the mighty Amazon, Pastaza encompasses some of the world's most biodiverse regions.
