What is nature? And who or what has a say in this? Are human beings the only ones who decide, or do plants, animals, bacteria, atmospheres, things and computers play a role as well? Yes Naturally puts anthropocentrism – centralizing the human position above all or interpreting reality exclusively in terms of human standards – in perspective. Is our arrogant placing of ourselves above all other agents in the world really justified? Is the DNA of a multicellular organism such as ourselves really so different from that of a virus? Our digestive tract looks remarkably like that of a sea squirt, which belongs to the most primitive of tunicates that have been around for more than 500 million years. And we have more in common with plants than we may on the surface suspect. Mitochondria are the energy producers of plants and animals: they are offspring of bacteria that lived in intracellular symbiosis with their hosts in an early evolutionary stage. Interconnectedness and interdependence are in fact the measure of all things.
