#22: Jesse van der Grient - Science without Sides
Dr. Jesse van der Grient is a quantitative ecologist whose work focuses on how ecosystems connect — across habitats, species, and stressors. She brings a neutral, science-based perspective through her work with the Deep Ocean Stewardship Initiative (DOSI), a network of experts that does not advocate for or against deep-sea mining, but provides the science needed for informed decision-making.
Jesse puts detials to the biology of the deep ocean and unpacks the interactions of deep-sea ecosystems and what they mean for the future of seabed mining.

Key takeaways
* “We need to understand what is being managed… the connections in the deep ocean people don’t always know about or understand very well.”
* “Two stressors can cancel each other out, or they can amplify each other. More often than not, we see synergistic impacts.”
* “Counting parts doesn’t tell you if the car works. In ecosystems, knowing species numbers isn’t enough — we need to know how it functions.”
