What they do is bury their garbage, especially the plant matter that is going bad. They have quite a garden, a good varety of plants they found in the jungle but that grow well from the garbage pit behind the cabin. Squash, potatoes, and peppers.
On the other hand, you probably do "know" these folks from a virtually identical "early agriculture development area" in the vicinity of Mammoth Cave, Kentucky.
They also domesticated many varieties of squash (otherwise a tropical plant), as well as the Jerusalem artichoke, and presumably other stuff.
Although these two places, Kentucky and Equador, seem far apart, if you have the use of boats....... well, we know what happens there ~ "the world" is discovered~
