Using Clouds to Map Ecosystem Boundaries

Elizabeth Borneman

Researching clouds and their impact on ecosystems and species could help researchers find an entirely new way to see the Earth. By looking at clouds, researchers can add a layer of evidence to existing theories and practices of conservation of land and animals.
