Which half? One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction. At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any controls?" Well the great surgeon drew himself up to his full height, hit the desk, and said, "Do you mean did I not operate on half of the patients?" The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind." Then the visitor's fist really came down as he thundered, "Of course not. That would have doomed half of them to their death!" God, it was quiet then, and one could scarcely hear the small voice ask, "Which half?" E.E. Peacock Jr., Seeing With Fresh Eyes science
The American lawn The American lawn uses more resources than any other agricultural industry in the world. The American lawn could feed continents if people had more social responsibility. Why should it be indecent to have anything useful in the front half of your property or around the house where people can see it? Why is it low-status to make that area productive? The condition is peculiar to the British landscaping ethic; what we are really looking at here is a miniature British country estate, designed for people who had servants. It has become a cultural status symbol to present a non-productive facade. The lawn and its shrubbery is a forcing of nature and landscape into a salute to wealth and power, and has not other purpose or function. The only thing that such designs demonstrate is that power can force men and women to waste their energies in controlled, menial, and meaningless toil.
