Well, what exactly does "sustainable" mean? If you take climate change as the impending complete disaster that some people see it as, it would kind of make it hard to sustain any ongoing development when it finally hits. Overfishing should be clear enough; run out of fish, and civilization hits a major setback that makes it hard to sustain whatever we've been up to. Gender equality and education access might be a bit more indirect, but at least so far our civilizational development has required a general upskilling of the population as a whole. And if you think that people are being excluded from that, then well a lack of additional people to upskill will turn into a blocker sooner rather than later and again make it hard to sustain that development.
