Natural Allies
Description
Have Earth's vibrant waterways-its streams, rivers, lakes, and oceans-become delivery systems for pollutants and poison? This program points to signs that toxic substances are overwhelming our planet's aquatic ecosystems. Viewers encounter many of the causes for this concern, including a radical decrease in frog populations, distressed marine mammals in estuary habitats, and disturbing changes in reef biodiversity.
