Showing graphs of water supply to large cities such as Brisbane, São Paulo, and LasVegas which have all become dangerously close to running out of water in recent years, David Sedlak goes on to describe four ideas to make urban water supplies more resilient, ideas such as maximizing rainwater collection. In LosAngeles, for example, they are building a natural treatment process rainwater collection park that collects rainwater through gravel filtered underground which can then be harvested. (I wish he'd mentioned limiting population growth in regions that exceed their water carrying capacity.) This is an important subject because urban areas that develop and grow, and consequently need more water usually expect to convert agricultural allotted water to urban. I watch as development and population growth continue to rapidly expand population here on the front range of Colorado and never is water supply questioned, as it is assumed some future solutions will always appear.
