"There are no scientifically justified obstacles to protecting biodiversity in all its beauty and diversity. There are only six years left to achieve the biodiversity targets by 2030. We must work together now to get there in time."In the 10 Must Knows from Biodiversity Science 2024, 64 scientists have further developed their well-founded and diverse findings and recommendations from the 10MustKnows22. The content of the ten selected key areas of the Earth-human system is supplemented by relevant publications from 2022 and 2023 and linked to the 23 global goals of the Kunming-Montreal Global Biodiversity Framework (GBF) adopted in December 2022. The authors are aware that the next six years until 2030 are essential for achieving an ecologically sustainable and socially just life on our planet in the medium and long term. With the 10MustKnows24, they want to actively contribute to accelerating the socio-ecological transformation by providing scientifically sound recommendations for politics and society.These are the 10MustKnows24: 1: Achieving climate and biodiversity protection together 2: Enabling a healthy life on a healthy planet 3: Considering undiscovered biodiversity 4: Linking linguistic, cultural and biological diversity 5: Harmonising the diverse use of forest ecosystems and biodiversity conservation 6: Transforming agricultural and food systems 7: Protecting land and resources 8: Releasing transformative change through international collaboration and Education for Sustainable Development 9: Ensuring free access and open use of biodiversity-related data 10: Reducing biodiversity impacts from food consumption

"Es gibt wissenschaftlich keine begründeten Hindernisse, die Biodiversität in ihrer Schönheit und Vielfalt zu schützen. Es bleiben nur noch sechs Jahre, um die Biodiversitätsziele bis 2030 zu erreichen. Dafür müssen wir jetzt gemeinsam anpacken."In den 10 Must-Knows aus der Biodiversitätsforschung 2024 haben 64 Wissenschaftlerinnen und Wissenschaftler ihre fundierten und vielseitigen Erkenntnisse und Empfehlungen aus den 10MustKnows22 weiterentwickelt. Die zehn ausgewählten Schlüsselbereiche des Erde-Mensch-Systems werden inhaltlich durch relevante Publikationen von 2022 und 2023 ergänzt und mit den im Dezember 2022 verabschiedeten 23 globalen Zielen des Kunming-Montreal Global Biodiversity Framework (GBF) verknüpft. Den Autorinnen und Autoren ist bewusst, dass die kommenden sechs Jahre bis 2030 wesentlich sind, um mittel- und langfristig ein ökologisch nachhaltiges und sozial gerechtes Leben auf unserer Erde zu erreichen. Mit den 10MustKnows24 möchten sie durch wissenschaftlich gesicherte Empfehlungen für Politik und Gesellschaft ihren aktiven Beitrag leisten, um die sozial-ökologische Transformation zu beschleunigen.Das sind die 10MustKnows24: 1. Klima- und Biodiversitätsschutz gemeinsam verwirklichen 2. Ein gesundes Leben auf einem gesunden Planeten ermöglichen 3. Unentdeckte Biodiversität beachten 4. Sprachliche, kulturelle und biologische Vielfalt verknüpfen 5. Vielfältige Nutzung von Waldökosystemen und Biodiversitätsschutz in Einklang bringen 6. Agrar- und Ernährungssysteme transformieren 7. Land und Ressourcen schützen 8. Transformativen Wandel durch internationale Zusammenarbeit und Bildung für nachhaltige Entwicklung bewirken 9. Freien Zugang und offene Nutzung von biodiversitätsbezogenen Daten sicherstellen 10. Auswirkungen des Lebensmittelkonsums auf die Biodiversität verringern

Purpose: Although diets are an important link between human health and the environment,knowledge on differences between dietary habits of population subgroups and how these link to differences in diet quality and environmental impacts is still limited. We therefore aim to investigate how different dietary habits in Switzerland perform with regard to human health and global warming potential, and which sociodemographic and lifestyle factors can be linked to different impact levels. Methods: We calculated the global warming potential and a diet quality score, the Alternate Healthy Eating Index, of recent dietary recall data from Switzerland (menuCH). The dietary recall data contained foods consumed during the last 24 hours as well as sociodemographic and lifestyle factors of the participants. Using multiple linear regression, we then calculated associations between sociodemographic and lifestyle factors and food choices on the one hand, and associations between sociodemographic and lifestyle factors and impacts on the other hand. Results of these regressions were then combined to shed light on how sociodemographic and lifestyle factors can be linked with impact levels via food choices.Results and discussion: Our results showed that performance of diet quality and global warming potential was particularly distinctive for age groups, language regions, nationalities, and smoking status, while education and income group seemed less relevant. Furthermore, some food groups offer synergies between diet quality and global warming potential when being reduced, such as different types of meat, dairy, and eggs. Thus, these food groups should be recommended and consumed with care, and their intake limited to the extent that they provide substantial added value in terms of nutrients provided. Other food groups, such as whole grains, pulses, nuts and seeds, vegetables, and fruits contribute to an improved diet quality, while having relatively low global warming impact intensities.
