Exploring the critical role of biodiversity in planetary health through groundbreaking research and innovative conservation strategies
Imagine our planet as a magnificent, complex machine with every species—from the microscopic bacteria to the majestic blue whale—acting as a vital cog and screw.
This is the rivet hypothesis popularized by Paul R. and Anne Ehrlich: lose one rivet, and the machine may function; lose multiple, and entire systems risk failure . As we navigate the challenges of the 21st century, biodiversity loss has emerged alongside climate change as one of our most pressing existential threats, with nearly 1 million species currently at risk of extinction 1 .
Species at risk of extinction
Of emissions reductions needed from nature
Of food crops rely on animal pollination
Biodiversity encompasses the vast variety of all living organisms—plants, animals, fungi, and microbes—across three fundamental dimensions: species diversity (the number of different species), genetic diversity (variation within species), and ecosystem diversity (the range of different habitats) 1 .
The World Economic Forum estimates that over $44 trillion of global economic value—more than half of global GDP—is moderately or highly dependent on nature 1 .
70% of emerging viral diseases have spread from animals to humans, with biodiversity loss increasing the risk of pathogen spillover from wildlife to human populations .
In one of the most comprehensive studies of its kind, a landmark 2025 paper published in Nature delivered unprecedented insights into how human activities are transforming biological communities worldwide 7 .

As we look toward the future, several promising approaches offer hope for bending the curve of biodiversity loss.
Recent research from the University of Helsinki provides compelling evidence for prioritizing biodiversity protection. Their analysis of 900 species over 20 years demonstrated that diverse natural communities are more stable over time than those with fewer species 3 .
"The findings help us understand mechanisms through which diversity boosts the stability and constancy of natural communities. They also help us identify communities that are particularly sensitive to environmental change, allowing us to target conservation measures where they are most effective."
The theme of the 2025 International Day for Biological Diversity, "Harmony with nature and sustainable development", emphasizes the vital linkages between the Sustainable Development Goals and the Kunming-Montreal Global Biodiversity Framework 4 .
Research in the Alps demonstrated that nature-based solutions offer a return on investment of 2.8:1 while providing heatwave mitigation, flood regulation, carbon sequestration, and landslide protection 8 .
Biodiversity is not merely a luxury of nature—it is the essential foundation of human survival, economic prosperity, and cultural identity.
The rivets in our planetary airplane are indeed loosening, but as the scientific community gathered at the 5th BCNP and XXXI RESEM understands, we possess both the knowledge and tools to tighten them.
