What about the public health? Even if each city is unique they all manifest a certain number of common problems like air pollution. Public health and the quality of the environment are highly interconnected.
For example, business parks can provide some interesting examples of public-private collaborations for turning areas of harm into healthy areas.
We can adopt in all cities environment-friendly activities, for instance public transport. Or Ensure proper ventilation of your house to reduce domestic air pollution.
Pedestrian tracks must be separated from roads by a row of trees and by that we can make cities less congested to allow proper ventilation and so on. By that we can attract enterprises from other impoverished environments stimulate the transformation of both areas and spaces of positive environmental and economic profit.
