The GMGI Science Hour with Dr. Ian Hewson

The Long-spined Urchin Mass Mortality of 2022: What Happened, What’s Happening Now, and Where to Go From Here.
Dr. Ian Hewson joins the GMGI Science Hour to discuss the impacts of the long-spined sea urchin's near-extinction in the Caribbean Sea in 2022.
What do sick sea urchins in the Caribbean have to do with us? If the sea urchin population is affected, it can have drastic effects on the entire ecosystem, including coral reefs. And the health of coral reefs is vitally important to human health - they help to regulate our climate and play a crucial role in nutrient cycling.
