Sustainable City Design

How would you create a city that does not produce more air pollution than the atmosphere can cleanse naturally?

In creating this more sustainable environment, consider livability, safety, and convenience.

First off, this service does not write your papers...however, I can offer germane direction in this area and/or give assistance in correcting an already written paper. However, I think this will give you sufficient fodder to create a one-pager.

Let us look at the variables that can contribute to degradation of air quality in approximate order of import. ( Keep in mind that urban smog is a phototlytic by-product of mixed pollutants):

1) Transportation - personal transport (cars, trucks, motorcycles) and public transport (buses, etc) that run on internal combustion technologies are *the* major contributors to poor air quality in urban environments. Pollutants include S-oxides, N-oxides, particulates, CO, CO2. Diesel & alcohol combustion may also produce significant levels of aldehydes.

2) Combustion of fossil fuels for heating, power generation - ~40% of US power is coal-fired. While many plants have scrubbers, often older plants are exempt (grandfathered in), or "trade" pollutant permits with other entities. Pollutants include S-oxides, N-oxides, particulates, CO, CO2, certain metals in coals as well (Se, Hg).

3) Industrial processes - aside from burning fuel for heat / power (such as waste for water heating or power co-generation such as above in 3), industry puts out a variety of ...
