I am not sure if such a word exists, but I figured it good to ask anyway:
I'm looking for a single word to describe something that has both better quality, and also higher quantities or volume of something.
e.g.
"Our oceans provide more quantity and better quality sustenance."
"Our oceans provide better sustenance."
Is there a way to avoid other dull words like "better" or "more"?

Near synonyms are plentiful, emphasizing "large amounts," and ample, emphasizing "more than enough

Galore means there’s so much that it’s unbelievable. The word is an example of a postpositive adjective, which means it comes after the word it describes. (vocabulary.com)
