“…Similarly, if electricity is still flowing, it could be used to electrolyze water into oxygen and hydrogen. These could be combined by specialized microbes to create food [121,122]. Combination catastrophes could occur with the sun being blocked and electricity/industry being disabled [123].…”

To safeguard against meat supply shortages during pandemics or other catastrophes, this study analyzed the potential to provide the average household’s entire protein consumption using either soybean production or distributed meat production at the household level in the U.S. with: (1) pasture-fed rabbits, (2) pellet and hay-fed rabbits, or (3) pellet-fed chickens. Only using the average backyard resources, soybean cultivation can provide 80–160% of household protein and 0–50% of a household’s protein needs can be provided by pasture-fed rabbits using only the yard grass as feed. If external supplementation of feed is available, raising 52 chickens while also harvesting the concomitant eggs or alternately 107 grain-fed rabbits can meet 100% of an average household’s protein requirements. These results show that resilience to future pandemics and challenges associated with growing meat demands can be incrementally addressed through backyard distributed protein production. Backyard production of chicken meat, eggs, and rabbit meat reduces the environmental costs of protein due to savings in production, transportation, and refrigeration of meat products and even more so with soybeans. Generally, distributed production of protein was found to be economically competitive with centralized production of meat if distributed labor costs were ignored.

“…For both scenarios, the percentage of dry weight of leaves that can be extracted as edible food for different tree species would also need to be experimentally determined. These techniques would need to be weighed against other solutions previously discussed in a partial sun-obscuring disaster as well as new solutions such as scaling up greenhouse crop production (Alvarado et al, 2020), microbial protein production from hydrogen conversion (Martínez et al, 2021), or biorefinery repurposing for sugar production (Throup et al, 2020). Finally, it may be possible that a lower caloric intake than the World Health Organization (WHO, 2012) recommendations is possible, so more clarity is required in the caloric input necessary to sustain human life to calculate the mass of leaf biomass that needs to be available in all scenarios.…”
