Hello.

Have I used "indispensable" correctly and naturally in this sentence?

Rivers are an indispensable part of the natural ecosystem in every country regardless of [STRIKE]the[/STRIKE] location. [STRIKE]of that country.[/STRIKE]

I'd use "vital". "Indispensable" sounds as if we have the option of removing all the rivers but choose not to.

Note how I would end your sentence above.
