Air pollution final.ppt
This document defines air pollution as occurring when air contains harmful amounts of gases, dust, fumes or odors. It discusses outdoor sources like smog and indoor sources like burning wood. Natural sources include wildfires and volcanoes, while human sources are things like vehicles, power plants, and burning wood. Air pollution can cause health issues for humans and environmental effects like acid rain. The document recommends mitigating air pollution through sustainable development, international agreements, and new technologies.

Editor's Notes
- #4 Outdoor Air Pollution: Each year, hundreds of millions of tons of gases and particulates pour into the atmosphere. Most of this pollution results from the burning of fuel to power motor vehicles and to heat buildings. Some air pollution also comes from business and industrial processes. Indoor air pollution occurs when buildings with poorly designed ventilation systems trap pollutants inside.
