The Amazon rainforest is the largest ecosystem in South America; it is the one that drew me into the study of geography. I know quite a lot about it, though I still have plenty to learn.

I know very little, however, about the second-largest ecosystem of South America: the Gran Chaco of Paraguay, Argentina, and Bolivia. It is also second in biodiversity, with over 500 species of birds alone.

"hunting land" and hinting at the region's diverse fauna.
I have even more to learn about it, especially as both the land and the people of the Gran Chaco are threatened by rapid changes related to the opening of a bioceanic transportation corridor. The Amazon experience is, sadly, instructive -- rapid expansion of roads is bringing all manner of peril. In both cases, heretofore uncontacted civilizations are at greatest risk.

The Gran Chaco is being traversed by road, rail, and river.
