(Suggestion @imccarthy)
  1. Not enough water
    I'm parched!
  2. Not enough food
    The land is fallow :(
  3. I thought I had some tampons under the sink
    But my roommate took them all
  4. Climate change
    There were like 40 in the package, I don't know how she did that
  5. Deforestation
    And she left the empty box so I didn't even know we needed more
  6. Unrestrained self-interest in the absence of regulations
    She really did it this time
