Until as recently as 1950, based on population locations, humans were considered a rural species (more people lived in rural areas than urban areas). However, since that time, humans have migrated to urban locations so that currently, 68% of all humans live in cities. This migration has led to issues such as urban sprawl, habitat destruction, and increases in waste moving in waste streams (solid, liquid, etc.). One proposal to solve these issues is to follow sustainable planning at the local level to reduce impacts. Write a paper that discusses the following: What is the primary objective of sustainable cities? What are the pros of this approach? What are the cons of this approach? Provide an example of a sustainable city design in the United States. How has this approach improved the quality of life for the individuals living in that city? Will current land-use practices support a growing population in urban centers? How does the idea of sustainable cities relate to the concept of smart growth? 350 Words Minimum, APA Citation, at least four external sources, such as peer-reviewed articles, websites, trade journals, etc.,
