Plants have always been humanity’s most constant companions. Plants are often underestimated as meek and unchanging components of our environment, but they are powerful shapers of human experience. They sustain global economies—including essentially all of our food—and shape aesthetic and spiritual values in many cultures. This course surveys the complex relationships humans have had with plants, touching on topics ranging from ecology to art, and poisons to passions. This course will change how you think about our leafy colleagues. Note: You may register for 19702 separately from 19701. If you register for 19701, 19702 is included.
