Feeding Everyone No Matter What: Managing Food Security After Global Catastrophe is a 2014 book by David Denkenberger and Joshua M. Pearce and published by Elsevier under their Academic Press.

The book analyzed five crop-destroying catastrophes (sudden climate change, super-weeds, super-bacteria, super-pests and super-pathogens) and three sunlight-extinguishing events (supervolcano eruption, asteroid or comet impact, and nuclear winter).

[1][3][4][5][6][7][8][9][10][11] Io9 writes that it takes into account potential realistic scenarios, such as crop blights and nuclear winter.

[9] Michigan Tech News interviewed author Joshua Pearce on the solutions presented in the book.

[20] The authors, David Denkenberger and Joshua Pearce, claim alternate food sources could feed everyone even if the sun is blocked by a catastrophe such as nuclear winter, supervolcano eruption, or large asteroid/comet impact.
