One quick, simple act can make all the difference. Planting a seed in the soil takes approximately five seconds. Watering and otherwise caring for that seed/plant requires roughly one minute per day. In the case of, say, a radish, you are looking at thirty minutes of your time (a.k.a. one episode of a TV show) to go from a dry seed to a deep red delicacy plucked from the garden, washed off at the faucet, and devoured by your one-year-old child (or something like that).
