Plankton – Invisible Climate Guardians

 

Anthéa Bourhis, an AI and plankton imaging analyst, collects plankton from the depths of the Mediterranean Sea and brings the samples back to the Villefranche Oceanography Lab (LOV) for storage and imaging.

Plankton sustain life on Earth: phytoplankton have produced more than half the oxygen we breathe, and zooplankton form the foundation of the marine food chain. Climate change threatens this fragile world, making research on plankton more important than ever.

Why there is no such thing as a natural disaster

Nature creates hazards. Disasters happen when those hazards hit vulnerable people and systems. When we say “natural disaster,” we ignore the choices that increase — or reduce — risk. And when we change how we speak, we can change how we act.

How National Biodiversity Strategies and Action Plans can save our planet

National Biodiversity Strategies and Action Plans (NBSAPs) are the primary frameworks countries use to implement global biodiversity commitments at the national level and drive action to halt and reverse nature loss. Learn about the importance of NBSAPs in translating international biodiversity targets into concrete policies, actions, and investments.
