Both plants were first cultivated and used for thousands of years in the Americas before being transported across the world to join the cultures where they are appreciated today.

Tsunami Troubles

Large earthquakes, volcanic eruptions, and tsunamis can create shock waves felt around the world – literally. The blast from the volcanic eruption on January 15, 2022, near Tonga caused spikes in air pressure recorded around the planet. We can add this eruption in a remote part of the Pacific Ocean to our knowledge of pandemics, climate change, and numerous other interconnections that tie our planet and our societies together.

Following Fossil Footprints – Part 1

Who left the earliest footprints in rocks that we can admire today? From the giant tracks of enormous dinosaurs to the delicate prints of small lizards and birds, I think footprints are fascinating. Tracks preserved for tens of millions of years, as well as those left within hours, can tell interesting stories about people, animals, and their interactions.
