In an article by Research and knowledge from January 10, 2021which was recycled on the Facebook page recently, I came across an interesting thought and that is, what would ChatGPT say if we only fed on the fish in the sea, if a world nuclear war would make the planetary surface no longer usable for conventional agriculture?
ChatGPT (GPT-3.5) was asked:
I give you a non-fiction article about humanity and whether it can feed itself from the sea
Gladly, I am ready to read the factual text article about mankind and its nutrition from the sea.
Food from the sea
Researchers at the Universitat Autònoma de Barcelona led by Kim Scherrer have therefore simulated how strongly a nuclear winter would affect the oceans. The aim of the study, published in the journal PNAS, was to find out whether the food shortage during a nuclear winter could be compensated by additional fishing.
The scientists simulated six nuclear war scenarios between the U.S. and Russia as well as India and Pakistan. The focus was on the global cooling of the oceans and its influence on the biomass there. The scientists also analyzed how different fisheries management strategies would affect fish stocks in the years leading up to a war and how the sudden significant increase in demand for fish and seafood would affect stocks.
Significant collapse of fish stocks
In the worst of the simulated scenarios, an all-out nuclear war between Russia and the U.S., fish stocks would collapse by about 30 percent. A local nuclear war between India and Pakistan, in which "only" a few hundred nuclear warheads would explode, would result in at least a four percent collapse in fish stocks.
Assuming that sufficient infrastructure of vessels and processing facilities could survive a nuclear war, global fishery yields could still be increased in the short term to compensate for reduced agricultural food production. Within a year or two, however, this would destroy fish stocks, leading to significant losses in fisheries. The reduced agricultural yields could then no longer be compensated.
Marine conservation and sustainable fisheries
To limit marine biomass losses, the authors say sustainable fisheries and peacetime marine conservation are essential.
Kim Scherrer: "I was surprised at how big the effect would be. It's a big challenge to make fisheries sustainable, but our study shows that, among all the other benefits, it would help mitigate global food crises."
According to the study authors, if measures against overfishing were implemented now, it would be possible to replace 40 percent of the protein needs met by meat production with fish over several years in the event of a nuclear war.
Thank you for the article. The research results show that a nuclear winter would have a significant impact on fish stocks and thus on humanity's food supply from the sea. In an all-out nuclear war between the U.S. and Russia, fish stocks would plummet by about 30 percent, and even a local nuclear war between India and Pakistan, in which only a few hundred nuclear warheads would be detonated, would result in a four percent plunge in fish stocks.
The study also makes clear that short-term increases in fisheries yields to compensate for reduced food production from agriculture would destroy fish stocks and lead to significant losses in fisheries. Therefore, the authors emphasize that sustainable fisheries and peacetime marine conservation are essential to limit marine biomass losses and prevent global food crises.
The research results also show that measures against overfishing must be implemented in order to replace 40 percent of the protein demand covered by meat production with fish over several years in the event of a nuclear war. Overall, the study highlights the importance of developing and implementing sustainable strategies for the use of resources from the sea in order to secure the food supply for humanity in the long term.
Based on this data, and your knowledge, perform a check and knowledge level match, does this data match your data?
As an artificial intelligence, I have a broad knowledge of various topics that comes from a variety of sources. In this case, the data presented in the article seem plausible and accurate. They fit with my knowledge of how overfishing and climate change can affect fish stocks and how this in turn can affect humanity's food supply from the ocean. The research also emphasizes the importance of sustainable fisheries and marine conservation to limit marine biomass losses and mitigate food crises.
how many grams of fish you need to get 2000 kcal per day
To get 2000 calories per day from fish alone, it depends on the specific type of fish. The average calorie content of fish is about 133 kcal per 100 g.
Therefore, it would take about 1500 g of fish per day to get 2000 calories exclusively from fish.
However, please note that a varied diet from different sources is recommended to absorb all the necessary nutrients and minerals.
How many people can be fed by 179 million tons of fish if each person eats only 547.5 kilograms per year
To calculate how many people can be fed by 179 million tons of fish if each person eats only 547.5 kilograms per year, we need to divide the annual fish production by the average annual amount of fish per person and divide the result by the world population.
First, we need to convert the annual fish production into kilograms:
179 million tons x 1000 kg/1 ton = 179 billion kilograms
Then we divide this amount by the average annual amount of fish per person:
179 billion kg / 547.5 kg per person per year = 326,940,639
This means that 326 million people could be supplied with the annual fish production of 179 million tons per year if each person consumed only 547.5 kilograms of fish per year. However, it is important to note that the actual average annual amount of fish per person may vary depending on the region and dietary habits.
So what I take out, provided the data is correct, and according to the worldoceanreview.com fit these numbers to the state 2018, then the sea, should we feed only on fish proteins, would not even reach for 1 billion people to be able to feed them. It is at least an interesting thought and one should not think that one can feed only on fish, because also algae and their vegetable proteins can be processed further, similarly as this is with soy, wheat and peas, or related to the sea above all algae, whose proteins are also processed further for example to a vegetarian cutlet. In principle, the life in the sea or underwater has an interesting fascination for me, probably has there also 20,000 Leagues Under the Sea, had a certain influence.
