earthrise - Sea Otter Cascade

In the Elkhorn Slough estuary of Monterey, California, the impact of heavy agricultural activity degraded the water quality and the marine habitat for the slough's vibrant species. After years of decline, however, the tide might be turning for seagrasses. In recent years, a hunting ban that allowed sea otters to return to the slough also turned around the fortunes of seagrasses. Yasmeen Qureshi explores the unique role that the return of the sea otters have had on the oceans of California.
