Microbiologist Marc-André Selosse said reducing chemical fertilizers could protect the climate and biodiversity during a special podcast recording in Paris [1].
The proposal highlights a critical intersection between industrial agriculture and environmental collapse. By shifting away from chemical dependencies, the global food system could potentially mitigate climate change and prevent further loss of species.
Selosse appeared as a guest on the "Chaleur humaine" podcast for an episode recorded at the Théâtre de la Ville [1]. The session was part of a larger festival of ideas that consisted of 10 episodes broadcast over 10 days [1].
The discussion focused on how an agricultural model that uses almost no chemical fertilizers could serve as a tool for ecological recovery. The event took place on Dec. 14, 2024 [1].
According to the program, the goal of the series was to provide actionable ideas for starting the year 2025 with a focus on sustainability [1]. Selosse said microbiology maintains soil health and provides subsequent benefits for the broader ecosystem.
The initiative sought to demonstrate that reducing chemical inputs is not merely a preference for organic farming but a necessity for climate stability [1]. The podcast emphasized that the health of the soil is directly linked to the survival of biodiversity.
“Reducing chemical fertilizers could save biodiversity and contribute to the fight against climate change.”
The emphasis on reducing chemical fertilizers reflects a growing scientific movement toward regenerative agriculture. By prioritizing soil microbiology over synthetic inputs, the approach aims to transform farming from a carbon source into a carbon sink, addressing both food security and the global biodiversity crisis.
