Why orphans?

A good question. The world has so many problems. Why focus on orphans?
I got these thoughts from: https://www.worldorphans.org/why-orphans/

Imagine a world faced with catastrophic issues, such as extreme poverty, disease, starvation, human trafficking, and the exploitation of child soldiers. At the core of those issues is one common link—the orphan. Currently, there are over 150 million orphans in the world . . . abandoned, neglected, and vulnerable.
In a world inundated with hypocrisy, people are constantly looking for something pure and faultless. James 1:27 reminds us that “Religion that God our Father accepts as pure and faultless is this: to look after the orphans and widows in their distress and to keep oneself from being polluted by the world.”
