but the problem is the food if it runs out
True, but they are actually working on ocean-based agricultural techniques so that seasteads can farm their own food locally and sustainably. And of course, land-based cities have that problem, too. Millions or probably billions of people already depend upon food shipping for our survival.
I understand, but where will they get the fresh water to water the plants since the salt water would surely kill the harvest, I will have to read the article you sent me in the first answer.
Because living in the ocean would be great but it also has its disadvantages since the sea is constantly threatened by storms and siphons, although on land we are also in danger of natural disasters that appear constantly.
And if we do not go to another planet, it will not kill solar radiation, frozen, or by consuming high carbon dioxide.
Hahaha I think I'm a bit optimistic.
It has been a while since I read about it, but if I recall about the agriculture correctly, there are three main techniques: they use solar-powered desalination for fresh water plants (and also for drinking water); they grow plants that thrive in salt water; and they use large cages to pen marine animals in and farm them.
You're right that there are challenges, though. I hope that the engineers who are working on it will be able to make it safe, but that remains to be seen.
I understand .. Desalination consumes a lot of energy if I remember correctly, I think that for drinking water they should use thermal desalination to evaporate the water to separate the salts and impurity from the salty water and to water the plants, reverse osmosis desalination could be used but this is more difficult since they should use a high pressure pump and pass through a series of filters.
Well the engineers will find a way to use high energy generators in the sea because otherwise desalination will not work.
