Today, only about 25% of the Earth is still in its natural, unaltered state. The rest of the terrestrial biosphere consists of human-altered biomes, called anthropogenic biomes or anthromes. The map shows the five main anthromes in the western United States. On this map, much of the land classified in the urban, or highly developed, anthrome is near the coast, while a large part of the wildlands is comprised of desert. What is one reason urban anthromes may be concentrated in coastal areas?
a
Coastal areas are less likely to have a variety of plants and animals than deserts.
b
Coastal areas are more likely to have large temperature fluctuations than deserts.
c
Coastal areas always experience natural disasters.
d
Coastal areas are more likely to have more available natural resources than deserts
