I think horticulture programmes are drastically underrepresented. It's one of the most interdisciplinary sciences that you can use to teach pretty much anything. In studying the dialectics between organism and environment I could teach every component of those interactions from soil to sky. Plants are deeply political and a great platform for left-urbanism, socioeconomics, and historical materialism discussions. Operating a greenhouse is an education in several trades, while being able to grow a plant builds important life skills. It's an excuse to take city kids into nature and show them why it's worth defending.
