The phrase "ongoing debate" refers to a discussion or argument that continues over an extended period, often involving multiple parties and perspectives. It is a topic that people are still discussing and trying to reach a conclusion on, with no clear resolution in sight. The issue at hand may be complex, contentious, and have far-reaching implications, making it difficult for all sides to come to an agreement. As such, the debate remains unresolved as different opinions and perspectives continue to clash, leading to a continuation of the discussion without any definitive conclusion being reached.
