This is a problem some of us have been aware of for at least 4 decades.
I am unconvinced humans are intelligent enough to stop their urges causing problems. Some even seem unaware that they are part of the problem for having more than 2 offspring, or if they are aware they don't seemingly care, thinking it is up to others not to follow but have none to compensate.
What is unforgivable is government actively trying to encourage births. Or in taking in the excess population from areas of the world who can not sustain the number of people they create allowing space for them to create more.
And the excuses one hears about needing a growing population, as if the future catastrophe can be just ignored as someone else's problem.
At the present state of an individual's ability to behave correctly, there are few options. One is a totalitarian state who enforces abortion according to various rules. This is a nightmare scenario. Another is for all the governments of the world to accept the problem and ensure large incentives to limit family sizes in their country. Many siblings is a luxury we can no longer afford.
But to sum up the answer to your question, I have no faith anything will be done, so you can only wait for nature to sort the issue out as another shortsighted species grow too large for it's food supply. That, or there is a major war just over the horizon. Maybe both if one causes the other.
