Use the graph to answer the question.
The vertical axis is labeled millions and ranges from 0 to 900 in increments of 100. The horizontal axis is labeled year and lists dates from 1700 to 2000 in 100-year increments. The line for population starts at 90 million for 1700 and with a slow growth rate reaches to 120 million by 1900. The line then rises with a high growth rate and reaches beyond 600 million by 2000. The line for steel consumption starts from 0 in 1860 and reaches 20 million by 1900. The line then rises with a high growth rate to reach beyond 800 million by 2000. The values used in the description are approximate.

With such huge increases in population, why has there not been a direct and equivalent increase in urban development (i.e., why is it such a small proportion of habitable land use)?(1 point)
Responses
There is not enough habitable land left for further urban development.
