-Ever since I first learned about outlining in high school (or was it earlier?) I've always loved being able to organize information hierarchically. The irony is that I also love biology and the natural world does not necessarily organize itself in a hierarchical way. Cross-pollination and inter-species breeding is a thing.\footnote{Don't get me started here. I could write an entire zine about this.}

 Fortunately, \LaTeX{} does have something simpler—the \texttt{outlines} package.
