It's difficult to survive in such an extremely hostile environment.
Is 'an' optional?
It's one environment (singular) so the article "an" is required. In the plural form we omit the indefinite article after "such".
This is such a good environment.
These are such good environments.
Also in the case of uncountable nouns we omit the article:
This is such good bread.
This is such a good bread. (Here, "bread" is countable.)
It is necessary in that sentence. This sentence is wrong: It's difficult to survive in such extremely hostile environment.
You can omit "an" in this sentence, which is very similar to your original: It's difficult to survive in such extremely hostile environments. This means that there is more than one extremely hostile environment.

Thanks, velisarius and owlman.
Separate names with a comma.
