Biology:Biodiversity

Biodiversity powers the planet

From the food, clothing and medicine available to us, to the vibrant lakes, forests and beaches we cherish, biodiversity enriches our lives. Explore how CALS researchers are studying the variety of life to feed more people, create healthier and more resilient communities and protect the environments we call home.
