That chunk of coal was once a green plant, a fern or reed that lived one million years ago, or maybe two million, or maybe one hundred million. Can you imagine one hundred million years? Every summer for the whole life of that plant, its leaves caught what light they could and transformed the sun's energy into itself. Into bark, twigs, stems. Because plants eat light, in much the way we eat food.
