"Seaweed: Humanity's Lifesaver in the Aftermath of Nuclear War"

A study suggests that in the event of a nuclear war causing a "nuclear winter," seaweed, particularly red seaweed, could serve as a resilient food source due to its ability to thrive in tropical oceans and increased growth from nutrient-rich water. Simulations show that within nine to 14 months, seaweed could potentially meet 45% of global human food demand, replacing 15% of current food consumption, 50% of biofuel production, and 10% of animal feed. The iodine in seaweed makes "indirect" uses valuable, and the intervention could potentially avert up to 1.2 billion deaths from starvation. The main challenge would be the rapid construction of seaweed farms.
