Earth Notes

The Colorado Plateau is one of North America’s human and environmental treasures. Ancient cultures have called this land of sun-baked deserts and lush mountain landscapes home for centuries. Earth Notes, KNAU’s weekly environmental series, explores the Plateau by telling stories of the intricate relationships between environmental issues and our daily lives.

Rooted in science and wrapped in human interest, the two minute long segments encourage listeners to think of themselves as part of the solution to environmental problems. Upbeat and informative, the program tries to foster hope and dampen despair about the environment, and motivate listeners to become more conscious and informed stewards of the Colorado Plateau.

A hundred years ago, migratory birds suddenly became much safer, thanks to the outrage of two Victorian-era Boston women. Their efforts led to passage of landmark legislation, the Migratory Bird Treaty Act. To mark the centennial of that important law, 2018 has been declared Year of the Bird.
