What will happen if human beings become autotrophs?

Answer 1

Instead of eating, we would produce our own food by means of inorganic compounds which would make us chemoautotrophs, or the sun which would make us photoautotrophs..

Answer 2

If human beings were to become autotrophs, they would be able to produce their own food through processes like photosynthesis. This could potentially reduce our dependence on external food sources and lead to greater self-sufficiency. However, humans are not evolutionarily designed to be autotrophs, so significant biological and physiological changes would be required for this transformation to occur.
