More than even a process, nature is an interaction. Nothing in nature exists on its own. Everything depends on everything else. Plants couldn’t live without the minerals in the soil from eroded rocks. Animals could not live without plants. Even if the animals are carnivores, somewhere along the food chain someone depended on plants. Plants could not live without water. Water follows the process of gravity, rains down on us and flows to the sea.
The sea is full of animals, that, like on land, are being born, surviving, eating each other, and dying. Their bodies nourish other animals and so it goes until the planet is consumed by the eventual death of the sun.
Within these processes and interactions we have what appear to be substances. These substances appear differently to different animals with their unique sensory apparatuses. A solid rock to us may look completely different to an octopus. We don’t know. We don’t see through the eyes of the octopus.
It is all one enormous continuity, always changing, always transmuting into something else. Nothing is ever completely destroyed. It always changes into something else.
