Answer:
B
Explanation:
While there are indeed many natural resources, the use and extraction of these resources has not always been done in an environmentally friendly way.
Potable water is still a scarce commodity and is slowly being supplied to the population. Despite the efforts, a combination of salt water infiltration into the water table and chemical spills from refineries and other industrial sites make water pollution a serious issue.
Urbanization caused many people to cluster into large cities. When a city was forming, many jobs began to open. People would leave their unstable farming, trading, fishing etc.. jobs in the rural areas for a more secure factory, office, business job opportunity in the city. This means that the population is distributed unevenly across the US, with the majority of people living in urban areas.

These countries, as well as the rest that lack volcanoes are all countries that are not lying above collision or submersion lines between the tectonic plates, nor have a hot spot beneath them, which is where the volcanoes appear. The best known is the 'Ring of Fire' in the Pacific, where most of the active volcanoes are.</span>
