What is Environment in Postman and why would you create one?

Answer

In Postman, the environment is set of key-value pairs that are used to store named settings.

Each named setting (variable-like placeholder) can have different value for each environment.

This way you can parametrize settings and when you switch the environment, the specific environment setting value will be used without the need to change all occurences of the setting everywhere in your requests.
