Consensos, Cambio climático, Catastrofes ambientales, abejas, consumo localResumen
Como complemento de un artículo previo (Grau 2022), presento cinco grupos de hallazgos que desafían posturas bastante establecidas en la comunidad de ecólogos y ambientalistas. 1) La incidencia de catástrofes de origen climático sobre la población y la infraestructura ha disminuido de manera dramática, en buena medida por el progreso económico. 2) Las poblaciones de abejas están aumentando, e incluso si disminuyeran, su efecto sobre la seguridad alimentaria del planeta sería menor. 3) Las estimaciones sobre los daños económicos de las especies exóticas frecuentemente son exageradas, sin un balance adecuado de costos y beneficios. 4) Por lo general, el consumo local no disminuye la huella de carbono y no tiene ventajas nutritivas. 5) El ganado europeo puede aumentar la diversidad de herbívoros y las comunidades asociadas, y puede contribuir a mitigar los efectos de las extinciones asociadas a los humanos originarios. Para promover una ciencia ambiental más rigurosa y menos dogmática, sugiero aceptar de manera más explícita que el cambio (incluyendo migraciones y extinciones) es parte constitutiva del funcionamiento de los socio-ecosistemas. Además, es necesario enfatizar que los cambios ambientales deben evaluarse mediante el análisis de tendencias de largo plazo, discriminando entre relaciones causales y correlacionales, y no por la mera apreciación de eventos discretos. También es fundamental preservar el rol ‘esencial’ de la ciencia, que consiste en valorar los enunciados en función de su consistencia con la realidad, no por su funcionalidad a determinadas agendas políticas o ideológicas. Finalmente, es importante incentivar de manera proactiva las iniciativas científicas que desafíen consensos o creencias dominantes, como motor de investigaciones creativas y profundas basadas en datos.
