One in every 17 women in Sierra Leone, Africa, will die during pregnancy or childbirth—that’s the highest maternal mortality rate in the world.

To help provide the time, attention, and resources needed to effect systemic change in the country, bestselling author and longtime Mental Floss contributor John Green just announced that his family is donating a total of $6.5 million over the next five years to the Sierra Leone branch of Partners in Health (PIH), an organization that supplies poor communities with medical resources and works with local governments to establish long-term healthcare infrastructure.

In a video posted on his vlogbrothers YouTube channel (which he runs with his brother, Hank) Green explains that the high maternal mortality rate is partly due to a large-scale shortage of basic necessities like electricity, running water, and transportation. Without electricity, nighttime deliveries are dangerous and refrigerating blood for transfusions is impossible; without running water, it’s difficult to sanitize tools; and without ambulances, the best option for women who need emergency cesarean sections is a long ride to the hospital on the back of a motorbike.

Because the solution isn’t specific to just one thing, the country pretty much needs to build a better healthcare system from the ground up. With the help of PIH and donations from Green and other outlets, Sierra Leone’s Ministry of Health and Sanitation is dedicated to doing just that. In the Kono District, they’ll hire more community healthcare workers, strengthen primary care centers, and build a Maternal Center of Excellence in the government hospital with an NICU, operating rooms, and more.

If you think it seems like those objectives might cost even more than $6.5 million to achieve, you’re right. PIH’s overall fundraising goal is $25 million in the next five years, and they’re already more than halfway there.

Green is hoping to raise a little over $1 million each year, and every dollar helps. If you have a few to spare, you can donate to the campaign here.

There’s also a group of matching donors who have pledged to match up to $120,000 in donations per year. If you can contribute $2000 or more and would like to join that group, you can email John for details at sparksflyup@gmail.com.

Sierra Leone might have the highest maternal mortality rate right now, but there are similar crises happening all over the world. With this endeavor, PIH wants to demonstrate that improving healthcare systems isn’t impossible and also be a guide for other organizations hoping to replicate their work.
