Now how many of you have ever gone to a state park or a national park where you had a big sign at the front saying, "Closed because human sewage is so far over this park that you can't use it"?
Cuantos de ustedes han ido a un parque estatal o nacional donde hay un letrero que dice, " Cerrado por exceso de aguas residuales humanas en este parque que no puede ser usado" ?
