The Value of Coralligenous Habitats

Dialogues économiques
What do we know about nature? Not a whole lot. According to estimates from the French National Museum of Natural History, we have identified between 1% and 10% of the species on Earth. Marine ecosystems have been greatly damaged from being exploited for our wants and needs, though we still know very little about them and the role they play. Whether it is for biology or economics, we should be diving deep into how these habitats are important on both a large and small scale. This is what Laure Thierry de Ville d’Avray, Dominique Ami, Anne Chenuil, Romain David, and Jean-Pierre Féral have demonstrated by studying a little-known Mediterranean habitat known as ‘coralligene.’

The True Price of CO₂

In 2024, a grim record was set: it was the hottest year ever recorded on Earth. The signs of climate upheaval are now visible to all, as global warming manifests itself in a rapid rise in extreme weather events. In theory, the solution is straightforward: we must stop burning fossil fuels. In practice, phasing out energy sources so firmly entrenched in contemporary societies is an immense challenge. To reduce CO₂ emissions, economists — trained in cost–benefit analysis — can help policymakers design strategies that are both effective and socially acceptable.
