Hardcover in clamshell box: City Sink is a design research proposal for a meta-park of dispersed landscape infrastructure to boost carbon stocks in biomass and through formation of long-term sequestration reservoirs for soil organic carbon in New York City and Long Island. City Sink research merges urban land-use lifecycles and the carbon cycle to describe a systemic response to elevated atmospheric carbon levels provoking climate change. The project is a model for reimagining urban landscapes as urban ecological infrastructure.
