• Almost half of the world's population currently lives in cities, and by 2050 that is projected to increase to 75%.

• Vehicles will be fuel efficent, zero emission and use high tech electronics  and sorftware to assist drivers in a variety of ways.

• The consecuence of improving technology is that it causes pollution.

Global warming. High carbon dioxide levels increase the air’s temperature. The greenhouse effect is a natural and beneficial process in which the Earth's ozone prevents heat from escaping into the earth atmosphere. 

1. Human illness. As pollutant levels increase, human exposure to toxins will also increase and the exposure to pollutants is directly linked to cancer and heart disease.
2. Economic effects. Because of the people illness the less productive employees and also students absent from school due to illnesses caused by pollution may miss educational opportunitie.
