Air pollution is one of the most pervasive environmental problems because atmospheric currents can carry contaminated air to every part of the globe. Most air pollution comes from motor vehicle emissions and from power plants that burn coal and oil to produce energy for industrial and consumer use. Carbon dioxide and other harmful gases released into the air from these sources adversely affect weather patterns and the health of people, animals, and plants.

That black smoke looks horrible. There are many chimneys like that around the world giving us bad air. Thanks for the pic Fransianne, it makes me appreciate areas with trees and fresh air more.
