Marc-André Selosse works on mycoses: the way the mushroom and the tree collaborate. One takes nutrition from the soil and other gives sugar back. In biology we now understand that organism, of which we think that they exist in their own right, are in fact collaborating with micro-organisms. They are feeding by them, fighting illnesses with them. We can’t properly observe an organism any more without also focussing on its bacteria. Organisms alone don’t exist, this is only our perception. Climate change messes up the inter-species collaborations. If only one if the organisms has to change its behavior, the collaboration can no longer hold. Both have to adapt, so the chances of survival diminish. Biodiversity however, is only something that is in the interest of man. Earth will flourish anyway, as it has proven in previous mass extinctions. Biodiversity is then only of esthetic or functional concern. But what we should keep in mind is that there is no natural equilibrium, no stable condition. In ecology, it’s a mess, it’s a constant struggle.
