The advent of agriculture was approximately 25,000 years ago. What has happened since then? Massachusetts Horticultural Society’s Senior Horticulturist Hannah Traggis will discuss how agriculture influenced civilization, and how changes in the last century have impacted our food and environment. She will also look at how the choices we make as consumers influence the future of food. This Friends of Wellesley College Botanic Gardens talk will be held October 21 at 1 – 2 at the Wellesley College Club, 727 Washington Street in Wellesley, and is free for FWBG members, $10 for nonmembers.
