Plants quietly run the systems everything else depends on
Photosynthesis is the reason the atmosphere contains breathable oxygen at all.
Chlorophyll absorbs red and blue light and reflects green, which is why leaves look the way they do and why autumn colour is simply chlorophyll draining away to reveal pigments that were there all along. Beyond colour, plants hold most of the planet’s size and age records: the tallest living things, the heaviest organisms and the oldest individuals are all trees.
