Final answer:
The ostrich approach refers to the act of ignoring or denying risks.
Step-by-step explanation:
The action of ignoring risks or pretending that they don't exist is called the ostrich approach. This term is derived from the behavior of ostriches, who are believed to bury their heads in the sand when faced with danger. In reality, ostriches do not actually bury their heads in the sand, but the phrase has come to symbolize the act of avoiding or denying risks.
