Planet Earth is going through a “human bottleneck.” Basically all of the Earth’s surface, large parts of the oceans, and even considerable parts of its crust are affected by human actions. These actions change key parameters of its geological, biological, and chemical composition and character. The planet has entered a period of what should be called “neurogeology”: the mental states and resulting actions of individual humans, groups of humans, and the collective mental states of all humans together are creating a new mode of planetary development that blends human infrastructure and technology with novel ecosystems, a higher chemical and geological diversity, an altered climate, and even entirely new life-forms.
