For those who find this interesting and want to spend a bit more time on figuring out the most impactful ways to help in the developing world, I highly recommend you check out Doing Good Better [1] by Will MacAskill.

He is part of the Effective Altruism movement and the book does a great job of breaking down the relative impact of different charities, whether to “earn to give” or participate directly through volunteerism, etc.
