Australia, the country destroying its own Great Barrier Reef on the altar of resource extraction (coal, etc), is promising to protect oceans? This commitment isn't worth the paper it's written on.
But these aren't the only problems the ocean is facing. Resolving other issues will help maintain the health of ocean ecosystems.
It's likely wishful thinking but possibly it will be harder to justify new coal mines etc if enough of these individual agreements are accepted. :shrug:
