In this essay, we propose a hack of existing models of environmental risk communication so that they will better address Anthropocene risks. We focus our discussion on a key area of risk communication: environmental risk visualization (ERV). Drawing on social-constructionist theories of risk and our own research on ERVs, we assemble criteria for designing and evaluating ERVs based on their hybrid collectivity---meaning their ability to collect agents around themselves over time and across traditional Modern divides between human/nonhuman, expert/nonexpert, and nature/culture. We test the criteria on two ERVs from the 2011 Fukushima disaster and discuss the resulting promises and challenges of an approach to risk communication motivated by hybrid collectivity.
