The Amazon Forest Butterfly Effect story is a fictitious metaphor.

A butterfly gently flaps its wings in the tropical rainforest of the Amazon River Basin in South America, and it may cause a hurricane in Texas, USA. This is the famous "butterfly effect".

The Butterfly Effect refers to the fact that in a dynamic system, a small change in the initial conditions can drive a long-term huge chain reaction of the entire system. This is a chaotic phenomenon. There are constants and variables in the development of any thing. In the process of development, the development trajectory of things has regularities to follow, but there are also unpredictable "variables", which often backfire. A small change can affect the development of things, which shows that the development of things is complex.

In 1963, American meteorologist Edward N. Lorenz analyzed this effect in a paper submitted to the New York Academy of Sciences.
