I blame PIX for that! Poor macaws, tamarins, jaguars and groupers! I barely see them any more! [/joke]*

Serious now. I think most people are aware monoculture is bad, but the text highlights yet another problem: every time the monoculture changes, the local fauna adapted to the previous culture gets wrecked. Specially given the situation, since those cacao farms relied on the local flora, but coffee farms don’t.

And I bet that coffee isn’t even for local consumption, but for exportation.

*explaining the joke

Real bills typically depict animals, including a tamarin (from a related species, Leontopithecus rosalia, also threatened):
Image I’m joking that, since PIX (a cashless payment service) makes the bills pop up less often, it’s also getting rid of the critters.
