You can do the same thing, as the costs come down, for the Carolina parakeet, for the great auk, for the heath hen, for the ivory-billed woodpecker, for the Eskimo curlew, for the Caribbean monk seal, for the woolly mammoth.
Você pode fazer o mesmo, conforme o custo diminui, com o periquito da Carolina, com o grande mergulhão, com a galinha do urzal, com o pica-pau-bico-de-marfim, com o maçarico-esquimó, com a foca monge do Caribe, com o mamute lanudo.
