Plus30 % de valeur nutritive en moins sur certains aliments essentiels comme le riz. Comment est-ce possible ? Une nouvelle étude confirme que l’excès de dioxyde de carbone, principal gaz à effet de serre contribuant au réchauffement climatique, fait chuter la concentration de vitamines dans les plantes.
