Earth Day 1970 - 2020: 50th Anniversary || Time Will Tell

This year marks the 50th anniversary of Earth Day. In the ensuing years, our population has doubled. We eat more meat, fly more often, use more energy, and produce more stuff. Fortunately, our understanding has also changed. Decades of careful observation have given us a detailed picture of how Earth is responding to our habits. The past is clear. What will the future look like? It depends on the choices we make today.
