There are 80,000 museums in the world. 1 For comparison, consider the fact that this number is 25-percent greater than the combined total of McDonald’s and Starbucks outlets. Museums are beyond ubiquitous. They work everywhere on every topic imaginable. Large and small, these institutions are poised to be important catalysts of significant changes. If museums work together they can shift our societies to be more just for all. From championing human rights, such as healthcare and housing, to building a diverse historical record replete with voices of every color, creed, and tax bracket, museums can make a difference.
