Stewart Brand is an author, environmentalist, and above all, best known for his work as the founder of the Whole Earth Catalog. In 1966 Brand was one of the first environmentalists to push NASA — already with satellites orbiting the Earth — to release a picture of the “whole Earth” from space. He believed that a photo could be a powerful image for the then very young environmental movement, and when it was finally delivered to the world by the US government in 1968, it helped push the creation of Earth Day in 1970. An eco-trailblazer from the start, Brand recently penned the Whole Earth Discipline: An Eco-Pragmatist Manifesto, his sixth publication which explores how the Earth and its people are propelled by three transformations: climate change, urbanization and biotechnology. Recently, our very own Editor-in-Chief Jill Fehrenbacher had the chance to pick Brand’s brain, finding a thought-provoking discussion where Brand confers his belief that nuclear power might just be our green energy savior.
