The article cites on the art, monuments, and society in Neolithic Britanny in France. The evidence for an early ritual complex that includes a series of carved menhirs sealed beneath the cairn of the Table des Marchands passage grave has been revealed during the excavations by Jean L'Helgouac'h and Serge Cassen at Locmariaquer. Monuments of passage graves extends right around the coast of Britanny, specifically to the area around Carnac and the Golfe du Morbihan. It is believed that there was a localized emergence of marked social differentiation in southern Britanny at the end of the 5th millennium before the Christian era.

The chaotic distribution and dispersal of phosphorus (P) used in food systems (defined here as disorderly disruptions to the P cycle) is harming our environment beyond acceptable limits. An analysis of P stores and flows across Europe in 2005 showed that high fertiliser P inputs relative to productive outputs was driving low system P efficiency (38 % overall). Regional P imbalance (P surplus) and system P losses were highly correlated to total system P inputs and animal densities, causing unnecessary P accumulation in soils and rivers. Reducing regional P surpluses to zero increased system P efficiency (+ 16 %) and decreased total P losses by 35 %, but required a reduction in system P inputs of ca. 40 %, largely as fertiliser. We discuss transdisciplinary and transformative solutions that tackle the P chaos by collective stakeholder actions across the entire food value chain. Lowering system P demand and better regional governance of P resources appear necessary for more efficient and sustainable food systems.
