Our era is one of significant and substantial loss, yet we barely have time to acknowledge it. The losses range from the personal grief of a single COVID death to the planetary disaster wrought by climate change. We are in an age of unraveling hopes and expectations, of dreams curtailed, of aspirations desiccated. What can we do? It has become clear that the cost of wealth creation for a few is enormous destruction for others. The marginalized and the vulnerable have been feeling the crisis for a long time. At the same time, we are denied the means of mourning the futures that are being so brutally curtailed. Sarah Jaffe shows how public memorialization has become more than a refusal or a protest: it is a path to imagining a better world. When we are able to mourn the lives, the homes, the worlds we have lost, we are better prepared to fight for a transformed future.
