Over time, air pollution can even cause permanent changes to your lungs. Like smoking does. You have good reason to be. Their lungs are still developing, and since they breathe faster and tend to spend more time outdoors being active, air pollution affects them much more. Air pollution and global warming - a double threat to the planet.
Air pollution is caused by burning coal, oil, gasoline and natural gas.
But as if smog weren't bad enough, burning these same fuels creates a second threat. It's carbon dioxide, the main greenhouse gas that causes global warming. All the carbon dioxide we release from cars, power plants and factories adds to the warming effect of the atmosphere. Studies show the world is getting hotter. Just as a fever puts you under the weather, global warming does the same for the planet.
