Pollution is a health risk in the city. The are recent research results linking childhood asthma to air pollution. This prompts people to live in the suburbs where there is cleaner air. However, as more people live in the suburbs the farther their homes are from jobs and the city centers. This distance is rarely serviced by public transport which means the daily commute to and from work must be done by car. 572 liters of fuel per car is consumed over a year in a 10 kilometer distance from home to work which generates the pollutants that cause childhood asthma. Thus, in their effort to save their children from childhood asthma, people unknowingly contribute largely to the asthma that occurs in city dwellers.
At the population increase rate of 10,000 people per year and an assumed rate of 2 people per car ownership, 5,000 new cars enter the city every year if all the 10,000 take suburban homes. This is a 2.86 million liters of fuel per year increase. If all people live in in-city high rise homes, this increase in pollutants is eliminated. Thus, a Real Estate Agent, like a Toronto Real Estate Agent, should be rewarded for every in-city homes sold to new people or transferees from the suburbs.
