I think you are, @marvin100
I said you couldn’t use the present perfect before “Before,” when that clause precedes the simple past. (The time sequence is incorrect.) ;
Present perfect tends to be paired with the simple present, such as
“Since they have been widely hunted for their ivory…walruses [mow] are no longer plentiful…”
Both clauses imply both situations ongoing. Of course, that’s not the meaning intended to be conveyed in this case because they are no longer (legally) hunted, and thus probably not hunted “widely” in the present.
