"Young viewers will explore freshwater ecosystems such as ponds and rivers, as well as marine ecosystems like coral reefs and the open ocean. They will learn that the animal and plant life found in water ecosystems make up communities that are as complex as they are beautiful. A hands-on experiment demonstrates what happens when pollutants get into ponds and lakes, while a visit with a marine biologist examines the oyster population of the Chesapeake Bay."--Container.
