In some of these areas, there's not enough water, there's no energy, it's going to cost tens of trillions of dollars to lay out the sewer lines and to build the facilities and to operate and maintain these systems, and if you don't build it right, you're going to have flush toilets that basically go straight into the river, just like what's happening in many cities in the developing world. And is this really the solution?
En algunas de esas zonas no hay agua suficiente, no hay energía, costaría miles de billones de dólares colocar las líneas de drenaje y construir las plantas, y operar y mantener los sistemas, y si no se construyen bien, serán solo escusados que, básicamente, irán a dar directamente al río como ocurre en muchas ciudades del Tercer Mundo. ¿Y es esa realmente una solución?
