Document Summary
Since the industrial revolution, the planet has undergone a significant mass urbanization. Brownfields are sites left contaminated by pervious land use. Typically, these sites are left abandoned or decaying. In cities such as detroit, these sites are often within urban cores. Brownfields are largely the result of short term planning, lack of accountability, and outdated environmental regulations. Food deserts emerge when neighborhoods lack access to healthy food options. Food deserts disproportionately effect the poor and immobile, as result of the car-based development of many cities during the 20th century. Urban surfaces absorb solar radiation and emit it back at different rates that grass and trees. Heat is also produced from buildings and cars concentrated in cities. Noise pollution is unwanted, and potentially damaging sound from daily processes within the urban form. Consistent loud noises found in cities can have a number of negative effects: psychological effects on humans and other animals, disruption of circadian rhythm, hearing loss.
