How important do you think photosynthesis is to humans?
Not at all. Those are plants, what do we care?
Kind of important, because we eat some plants.
Important, animals eat plants, and we eat both plants and animals.
Incredible important - all life on earth would stop if plants couldn't photosynthesize.
