The creators of “Arcadia Earth” want to awaken your conscience. But they also plan to make that guilt trip extraordinarily fun.

Entertainment, coupled with enlightenment, is the purpose of this pop-up exhibition about ecological crisis, which opened at the end of August in Manhattan. An immersive experience consisting of 15 rooms, “Arcadia Earth” combines video projections, augmented reality and virtual reality with installations by more than a dozen environmental artists.

Together, they evoke the landscapes, marine depths and life-forms that global warming threatens. In “Oxygen Oasis,” featuring the work of Justin Bolognino, Eric Chang and others from the company META, you see orbs of light float upward and proliferate, a metaphor for how phytoplankton make oxygen.
