ON THE COVER
A seagrass meadow
in Cenderawasih Bay,
West Papua, Indonesia.
Seagrasses fringe the
coastlines of nearly
every continent on
Earth. These plants
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.
