David W. Orr, editor of the new book “Democracy in a Hotter Time” and a professor at Arizona State University, discusses the climate crisis as an obviously bipartisan issue; why building “Democracy 4.0” must ultimately be a localized, grassroots mission; and why, in our “long emergency” that is the climate crisis, we must “stretch our hearts to reach out to other species and future generations.”

Architect, writer, and curator Pedro Gadanho, author of the book “Climax Change!” and a Loeb Fellow at Harvard University, discusses how architects must increasingly innovate through densification and adaptive reuse rather than building anew; existing buildings as “material banks”; and the importance of downgrading our consumption levels, particularly in the Western world.

Astronomer Chris Impey, author of the new book “Worlds Without End: Exoplanets, Habitability, and the Future of Humanity” and a professor at the University of Arizona, discusses the vast possibilities of extraterrestrial human habitation, why imagination is an important form of scientific speculation, and why humans’ initial move to space will likely mirror the lawlessness of the Wild West.

Architect and novelist Lesley Lokko, the founder and director of the African Futures Institute and the curator of this year’s Venice Architecture Biennale, discusses how, for her, the rich context of Africa has always served as a “testing ground for ideas” about the future; why she has become disenchanted with the academic establishment over time; and how architects serve as translators between the imaginary and the real.

Táíwò, author of the books “Reconsidering Reparations” and “Elite Capture: How the Powerful Took Over Identity Politics,” speaks with us about why future decision-making will be driven by the state of climate politics, considering the deep presence of the past within the current moment, and what a planetary “solidarity economy” could look like.
