No dependency on plants: We and other animals would not be dependent on plants for any sort of food source and plants would be able to grow and flourish better increasing the overall scenic beauty of our planet which somehow is getting devastated because of human food needs.

No requirement of waiting for food in malls to getting the body recharged:

If we were able to prepare own food, we would never be getting tired due to lack of energy, we would always be creating our food side by side during daily activities without the need of spending lots of time and money on food courts.
