Q&A with Dr. Heather J. Lynch: How Antarctic Penguins Reveal the Health of their Ecosystem

Antarctic penguins signal the health of their ecosystem. Researchers study three penguin species to understand the krill population. Krill is vital because it supports many animals in the region. Penguins face competition from the krill industry, but fishing practices aim to protect them. Rising temperatures draw new penguin species to Antarctica, affecting the local ecosystem. Plastic pollution is a growing threat, found even in this remote area.
