We do not have an appropriate tool to investigate the circulation driven by the activity of organisms. Ecology and biology, two of the central sciences of organisms, are not very useful to this purpose. Geochemistry seems promising to understand the most outer line of biology. Let me see how far I can tackle the problem using geochemistry. .
