Broadway: 1000 Steps is an initiative to establish Broadway as the new “green corridor” of New York City where current and planned sustainability initiatives, such as those outlined in the City’s PlaNYC, will be made tangible to its citizens. Twenty “hubs” dispersed along the length of Broadway will serve as sites for collaboration between Mary Miss / City as Living Laboratory (MM/CaLL), artists, research scientists and other experts, municipal policy makers, academic partners, and local community groups. Installations, which are small in scale but aggregate to reveal the vast network of systems vital to a sustainable city, are designed to make sustainability tangible to citizens at street level and catalyze future projects by artists and environmental designers along this corridor. The sense of incremental transformation—of many individual instances working together to create a powerful cumulative effect—is the overarching idea for the project and the basis of its title: “1000 Steps”. The central message to be communicated – generated out of a year-long collaboration with a prestigious scientific and community advisory board – is that nature is everywhere and in action at all times, that the city is an urban ecosystem, that an innumerable number of small decisions over time have shaped the environment to be the one we inhabit today, and that our decisions (behavioral choices) impact the future of all of nature.
