Editing Brazil nut (section)

==Distribution and habitat==
The Brazil nut is native to the [[Guianas]], [[Venezuela]], [[Brazil]], eastern [[Colombia]], eastern [[Peru]], and eastern [[Bolivia]]. It occurs as scattered trees in large forests on the banks of the [[Amazon River]], [[Rio Negro (Amazon)|Rio Negro]], [[Tapajós]], and the [[Orinoco]]. The fruit is heavy and rigid; when the fruits fall, they pose a serious threat to vehicles and potential for [[traumatic brain injury]] of people passing under the tree.<ref name="ideta">{{cite journal |vauthors=Ideta MM, Oliveira LM, de Castro GL, Santos MA, Simões EL, Gonçalves DB, de Amorim RL |date=2021 |title=Traumatic brain injury caused by Brazil-nut fruit in the Amazon: A case series |journal=Surgical Neurology International |volume=12 |pages=399 |doi=10.25259/SNI_279_2021 |pmc=8422441 |pmid=34513165}}</ref>
