By enabling us to increase our efforts, we'll be able to ensure that not only all kids who were in school, including girls in those vulnerable groups before the pandemic, are able to return but also that we can pick up the great work that was generally happening around getting more students in school.
Over the past couple of decades, we've made a lot of global progress, including in complex situations like Afghanistan, in terms of getting girls in school at the same level as boys in many places, and really reducing that gap. There is a real risk that we're going to backslide on a lot of the progress made. We know about all the knock-on effects regarding schooling. You've heard this before. It's not just a place to learn. It's a place for children to flee violence, and where we're able to deliver immunization and malnutrition programs in many cases.
We know the interventions that work. Many organizations here are utilizing them. It's just the scale that needs more effort put into it. We did some analysis at Save the Children. It would require $50 billion worldwide to get all kids back in school who are out of school right now. Those are not just donors, those are national governments prioritizing it in their budgets. It needs to be an all-in effort in terms of how we are using our political will to prioritize these efforts.
