Scientific model
Deep ecology and animal rights say nature should exist only for itself. Human morality should be about leaving it alone. This ideology says to focus only on working to conserve habitat, increase biodiversity, and buy moral to not help damage things. It says to do all this without any measurable direct benefit to humans, even themselves. Humans are more like caretakers in this view which is often part of religion. It puts ethical limits on the actions of scientists, for instance it argues against animal experiments or genetically modified food. It usually is seen as opposed to science, not part of it. Its models of nature are not usually accepted by most scientists, but they matter in politics.
