In England, otters—which nearly disappeared in the 1970s—have made a remarkable comeback, a sign, Environment Agency officials say, of much greater good news.The use of pesticides—and the resulting toxic runoff that polluted rivers—where the otter's major challenge. Since the 1970s—when populations hovered near extinction—many of those chemicals have been banned.

Now, otters have reached maximum populations—limited only by their own territorial nature—in rivers across England. "The recovery of otters from near-extinction," Paul Raven, head of conservation and ecology at the Environment Agency, said "shows how far we've come in controlling pollution and improving water quality."

He added that:

The otter is at the top of the food chain, and as such is an important indicator of the health of English rivers.

Thus, healthy otter populations signify healthy rivers and ecosystems across the country—a clear sign that conservation efforts have been successful.
