Michael Wang uses systems that operate on a global scale as media for art: climate change, species distribution, resource allocation, and the global economy. His works include Carbon Copies, an exhibition linking the production of artworks to the release of greenhouse gases; Extinct in the Wild, a project that engages species that no longer exist in nature but persists under human care; World Trade, a series tracing the trade in steel from the World Trade Center following the attacks of September 11, 2001; and Rivals, a series that connects the readymade to systems of corporate finance.
