So called "developed" countries were once similarly careless with their waste. And their developed status was a result of such carelessness and the free expansion of their industries. It seems slightly unfair to expect developing countries to achieve a similar level of development via a sustainable methodology immediately, when that has not been the path for the richest countries in the world. (Given that developing countries are likely more concerned about the health of their population, and as such, focused on raising GDP, then the health of the ocean). Skipping to sustainable-led development is not impossible and obviously would be hugely advantageous for all, but it is still equally unfair to assign blame to such countries and label them as careless.
