> And before we go into “rights”, just because a country irresponsibly has a larger population, doesn’t mean that country has unilateral rights to destroy the oceans.

People aren't "irresponsible" for being alive, and nation-states aren't individuals who can exercise the kind of moral responsibility you're alluding to. You seem to be implying that countries like China should have gone even farther than measures like the inhumane and authoritarian One Child Policy.
