Assessing global catastrophic risksCertain nightmare events will be nearly impossible to endure as a species. For example, total nuclear war could easily render the planet inhabitable for the vast majority of life, including humans. Previous work frequently examined urban agriculture techniques such as community, home, and rooftop gardens for resiliency planning. These can take the form of community farm projects, as well as community members petitioning local leaders to focus on land use and zoning policies that support agriculture. “I’m skeptical that some ‘billionaire bunkers’ will be particularly useful post catastrophe if civilization actually needs a reboot,” says Boyd.
