removed the relative clause, who do not eat meat, we would be left with the following sentence:

*People are called vegeterians.

Which people are vegeterians? All? Definitely not! Only those people who do not eat meat. Therefore, the relative clause is a MUST here. It simply specifies which people are vegeterians; it defines the noun from the main clause.

It gives additional information and therefore it can be omitted without causing any confusion or changing of the meaning. As it is an additional piece of information for the meaning of the sentence, we put it between commas.

very beautiful city.

If we removed the relative clause, which has a population of one million, we would be left with the following sentence:

Dublin is a very beautiful city.

As we know the city of Dublin well, the information in the ralative clause, which has a population of one million, is only additional and the sentence without it is understood correctly. The relative clause is put between commas, as it can be omitted.

She is an actress who/that was awarded an Oscar.

In non-defining relative clauses we cannot use that instead of who/which.
