If international prices change, this would harm Mexico's finances. This has already happened in Mexico's recent history:
When the 1973 Oil Crisis hit the developed world, Mexican Presidents Luis Echeverria and Jose Lopez Portillo began to rely heavily on oil exports to support the financial needs of the country, taking advantage of the high oil prices. When the market eventually stabilized, the little diversification of exports resulted in an economic slump and a devaluation of the Peso by 500%. This is often called the Lost Decade or Decada Perdida (1973-1982).

In manufacturing good or rendering services, the wise use of resources could best be called economy. But the trick in this question is the word "wise," which is a subjective term. The above definition did not take into account just how scarce a resource is. If it is endangered, "wise" might involve not only the efficiency with which a resource is used, but also considerations of sustainability. We don't want to harvest so much of a resource that it becomes extinct.
It is a "contained" problem that affects most industrial areas throughout the country. Depending on the specific area, there are places within Mexico with a really bad pollution problem (especially on manufacturing cities along the US-Mexico border) while there are others with almost pristine environments, due to them being tourist areas which depend on beauty and minimal ecological footprint to operate. A couple of contrasting examples are provided on the "related links" section.
