Is "which" necessary to use here?

Yes, "which" is necessary here because it is used to introduce a new clause, or give new information and add on to a previous sentence. Without "which", the sentence would be run on and would not be grammatically correct. Here's some examples of "which": Ex: Australia, which is both a country and a continent, is home to many unique animals. Ex: Sometimes his friends call him Mac, which is a nickname.
