> Human beings don't directly photosynthesize for clear reasons.

I've always wondered why humans did not evolve to photosynthesize, and am interested if they could be permitted to evolve to using CRISPR.

Photosynthesis is terribly inefficient, something like 5-6% of the light is actually used to make glucose out of CO2 because the process is quite complex and humans don't have a huge skin surface.

That's my opinion

That's easy to solve. We just start growing leaves.

Remember, it doesn't need to be terribly efficient. Just efficient enough. I agree that its probably 100-200 years off though (if it can be done at all).
