COVER A seagrass meadow in Cenderawasih Bay, West Papua, Indonesia. Seagrasses fringe the coastlines of nearly every continent on Earth. These plants naturally combat pathogenic bacteria in the ocean and reduce disease. However, human activities and climate change threaten to destroy this ecosystem, which would affect the health of millions of people, as well as marine life. See page 731.
