Entropy -- badly put, the tendency of any isolated system to evolve to a state of maximum disorder. Luckily, most everything that exists does not exist in isolation, and 'energy' all all kinds/forms is continually flowing into every system to maintain a measure of stasis/status quo.
Golf courses are example of such systems, but watching major championships for many years and looking ahead to the championships to come, I can't think of any systems other than St Andrews-The Old Course that would not fall victim to the forces of entropy and become utterly unplayable save for the energy (time, labour, money, thought, talent, chemicals, water, grass seed etc etc) that humans throw its way, massive, continual, excessive amounts of energy.
Which is to say that yet again The Old Course (as you know, the answer or at least a viable answer to every question ever posed on gca.com) demonstrates its unique and unparalleled architectural/design genius.
