City X has a linear model of production.

Explanation:

First of all, City X does not provide a sustainable and stable ecosystem. It continuously brings resources from the outside and returns waste to the outside. City X's ecosystem is basically a one way drain pouring waste and pollutants on the environment.

This is an increasing tendency that affects the whole world. In 2009, for the first time in human history, more people live in cities than on rural areas. That has increased the amount of resources that cities need to survive, specially in very densely populated areas. And on the other hand, it has increased the amount of wastes produced by large cities that must be disposed somewhere else.
