What does photosynthesis do.
Photosythesis makes the food for the plants, and releases oxygen for humans. If photosynthesis never existed, we would be dead way before I typed this, if the plant is still alive its went through photosynthesis. If it didnt then it would die, if no photosythesis then theres no oxygen, no oxygen equals no air to breathe, no air equals no humans.
