Start by reading up and talking about the Carter Center. I've been donating to them for many years because they take a top down charity approach instead of just tossing money at a low level problem that never actually fixes the systemic reasons for which its a problem to begin with. The Cater Center takes an intelligent, high level look at how to ease human suffering and considers if its tangible to address from top down then DOES it. Take for example the Guinea Worm, a painful and sometimes disabling affliction that effected 3+ million people in 1985. In 2022 there was only 13 reported cases. It only took education and giving locals tools to project themselves from the larva. There are many examples of this that Carter through the Carter Center has left the world a substantially better place than he found it.
