BIO ATC Effects of Urban Regeneration on the Accessibility of Housing Discussion

I’m working on a environmental science writing question and need an explanation to help me learn.

Boulder, Colorado, has been a leader in controlling urban sprawl by limiting new construction and population growth. One consequence has been skyrocketing housing prices. Write a short essay of at least 1 1/2 page discussing issues related to the impacts of the housing price increase on the availability of housing for poorer people. Do you think this limit on who can live where is moral or ethical? With this in mind, also discuss the impacts of urban renewal on the availability of housing and urban sprawl (urban renewal is very common). How does this practice of renewal impact the poor?
