Studies have shown that when a nuclear war breaks out, burning cities and forests will emit large amounts of smoke and dust, blocking out sunlight. In the first year of the nuclear winter, temperatures could drop by 9 degrees Celsius and global food production could drop by 90 percent.
Scientists conducted simulations and found that in some areas seaweed can still grow at a rate of up to 13% per day in some areas. They estimate that seaweed grown on the ropes between the buoys can provide 15 percent of human food, 10 percent of animal feed and 50 percent of biofuel.
"We're going to need a lot of food because our current food system is no longer working," Jenn said. To get food quickly and on a large scale, seaweed is definitely one of the first choices. ”
While some areas are still suitable for terrestrial crops and seaweed, large-scale expansion of seaweed cultivation during the nuclear winter presents challenges. But growing more seaweed will make our food system more resilient.
However, Harry Flelich points out that while increasing seaweed production can increase the resilience of food**, there is still uncertainty about how many people seaweed will be able to feed after a nuclear war.
Therefore, it is crucial to start growing more seaweed now. What do you think humanity can do to make food systems more resilient? Feel free to leave a message to share your thoughts!
