“We are as gods and might as well get good at it.” This is the audacious opening line of the Whole Earth Catalog, a compendium of weird and wonderful tools compiled by counterculture legend Stewart Brand. A psychedelic experimenter, cyberspace pioneer, and environmental futurist, Stewart Brand is now urging humans to use our god-like powers to reframe our relationship with time and resurrect extinct species.

Stewart and scientists travel to Siberia to collect mammoth tissue and visit the once and future home of the Wooly Mammoth. Former allies in the environmental movement push back against reviving extinct species, but Stewart forges ahead in his long-life mission to conserve ecosystems.
