SEAGRASSES AND MANGROVES

They are an ancient species of flowering plants that grow
submerged in all of the world's oceans. Seagrasses link offshore coral reefs
with coastal mangrove forests. Today, these "prairies of the sea," along with
mangroves, are on the decline globally. Scientists fear the diminishing
vegetation could result in an ecosystem collapse from the bottom of the food
chain all the way to the top. Changing Seas joins experts in the field as they
work to restore Florida's important mangroves and seagrasses.
Known as
"hotspots of biodiversity," seagrasses and mangroves attract and support a
variety of marine life. However, worldwide damage and removal of these plants
continue at a rapid pace. Changing Seas travels along Florida's coastline to get
a better understanding of the significant roles mangroves and seagrass play
within the state. Can biologists prevent a negative ripple-effect throughout the
marine food web before it's too late? How will rising sea levels impact these
plants as well at the communities that depend on them?
