Why is binomial nomenclature important

To make a universal name and avoid the confusion of many vernacular names of the organisms.

Explanation:

There are many organisms living in different parts of the world. They are known by their respective local names called vernacular names. These vernacular names can't be understood universally. Therefore, there should be a standard name for every organism. These names are their scientific names. Every organism has a scientific name which is based on binomial nomenclature. This type of naming consists of 2 part of a species one is the generic name and other is species name.  For example, Mangifera indica is the scientific name of Mango where Mangifera is a generic name and indica is a species name. This type of names avoid the confusion of vernacular names of the organisms. Hence binomial nomenclature are important.
