Meet Alex, a first-year Environmental studies student at the University of Waterloo. Alex grew up in a small town where sustainability wasn't a common topic, and now they're excited to deepen their understanding of environmental issues. However, the urban campus life and abundance of social interactions have introduced Alex to some colloquial terms they're not familiar with, hence their innocent inquiry about “B.O.” – a concept potentially foreign to someone who spent more time in nature than around bustling city life.
