What is one question you have about the study of life? 3-4 sentences

my research into Sustainability Engineering, Time Use shows itself to be a very important variable. Together with ecological impacts (Ecological Footprint or Planetary Boundaries), Time Use to meet needs is a required unit of measurement. I am using both Max Neef's theory of Fundamental Human Needs, and Doyal & Gough's theory of Human Need.

hope you like the explanation.

thanks-:)
