Restaurando os rios da América: Preparar para o futuro


Communities across the nation are facing increasingly extreme storms that bring damaging floods. These events can strain outdated infrastructure and endanger public safety. Restoring America’s Rivers tells the story of how community leaders around the country are solving these problems by working with nature, not against it. Dams are being removed and levees are being set back in an effort to restore floodplains and give our rivers room to spread out, while making communities safer and more resilient to weather extremes, and restoring vital habitat for fish and wildlife.
