The exhibit depicts the adverse impact of school closures and called on nations to end them.

The installation features 168 empty desks, each seat representing one million children living in countries where schools have been almost entirely closed since the onset of lockdowns.

UNICEF, the World Bank, the World Food Program, and the UN refugee agency are asking countries to open schools as soon as safely possible. The agencies have worked together since last June to create a framework for opening schools safely. The UN believes it is more crucial than ever to get children back into a learning environment, according to Robert Jenkins, UNICEF's Global Chief of Education.
