In the past half-millennium, a number of animal and plant species have been introduced either deliberately (rabbits, cane toads, kudzu) or unwittingly (rats, green crabs) in biotopes where they proliferated and became pests.
This challenge is about adding capybaras to the list. By whatever plausible means, find a way for this rodent to be introduced outside of its native South America and proliferate to the point where it begins to displace local competitors.
