Hundreds of pairs of shoes, adorned with personalized messages tucked under their worn soles, represent the lives lost to Hurricane Maria, which decimated Puerto Rico, its people, and its infrastructure when it made landfall on September 20, 2017. The shoes are part of a new memorial in front of the Capitol building in San Juan, Puerto Rico, to commemorate the 4,645 hurricane-related deaths—a number that, according to a Harvard University study published in The New England Journal of Medicine in May, is more than 70 times greater than the death toll originally reported by the media. The shoes are symbolic of the failures of the US government to care for its citizens, of the tragic consequences of global climate change, and of the willful negligence and oversight perpetuated by colonialism. They are also a haunting call to action for activists and socially conscious individuals: Global disasters are all our responsibility and require crosssector collaboration and effort. To quote Audre Lorde, the black lesbian writer and daughter of Caribbean immigrants to the United States, “There is no such thing as a single-issue struggle because we do not live single-issue lives.” And when it comes to solving a problem like the devastating impact of Maria, we must think and act not only across sectors, but also across issues and across identities, in order to create systemic change.
