Ok I have been thinking genetics is that part of biology wich has the ability to change the genes of an organism as such it changes their abilities as well if so why cant we use this technique to change the problems that we face for example: The cells of plants contain chlorophylle as such they can create their own food thanks to sunlight+water+CO2 what if we take the gene responsible for this and transfer it to a human being like this he will not have any need to eat(but he still can if he wants for more energy like meat-eater plants) however a downside would be green skin but I think is worth another one would be the lizards wich have the ability to regenerate limbs and other body parts that were lost this can help those who suffer from absence of body parts. Wouldn't this be amazing like a human with different abilities to adapt and survive these that I mentioned are simply core of our problems these days there can still be more to it. SO why isn't this technique used for a solution to our problems?
