China, with over a billion people, is the biggest source of pollution in the world.
Until recently, the United States was the largest consumer of energy in the world– and the biggest polluter. Now, China has overtaken the United States as the worlds biggest producer of carbon dioxide.
New York City has the worst air quality in the United States.
The city with the highest level of smog and particles is Los Angeles, California.
Ozone is a powerful chemical that causes asthma attacks.
Ground-level ozone molecules, which are formed by vehicle exhaust and some other industrial chemicals mixing in strong sunlight, can make breathing difficult. For people with respiratory diseases such as asthma, exposure to even a small amount of ozone can cause an attack.
Acid rain is produced by air pollution.
When there are large amounts of pollutants in the air, the pollution can become concentrated in precipitation such as rain, fog and snow. Such precipitation, known as acid rain, can cause severe damage to human health, plants, buildings and automobiles.
Trees produce carbon dioxide.
Trees actually produce oxygen, but they need carbon dioxide to breathe. While planting trees helps the environment by helping to scrub excess carbon dioxide from the air, the type of trees that are planted can also make a difference. If you plant deciduous trees around your house, they will provide shade during the summer but light and warmth in the winter — cutting back on air-conditioning and indoor heating.
Hybrid cars are a cross between light trucks and automobiles.
Hybrid cars are a cross between electric vehicles and traditional gas-powered vehicles. A hybrid car uses much less gasoline than a regular car, leading to fewer emissions.
Burning fossil fuels produces some of the worst air pollution.
Burning fossil fuels, such as coal, gas and oil, produce emissions which are a major cause of pollution. The biggest users of fossil fuels are automobiles, factories and power plants.
Ozone protects you from cancer-causing UV radiation in sunlight.
When it is 25 miles above the earths surface– high up in the stratosphere– the same ozone that is so harmful to us on the earths surface keeps us healthy. How? By acting as a protective layer that shields all living things from ultraviolet radiation from the sun. Too much ultraviolet radiation can lead to skin cancers, reduced crop yields and disruptions in the marine food chain. Pollution damages the ozone layer, which allows more UV radiation to reach us.
Turning on the television causes air pollution.
The appliances in our homes, schools and offices use energy that is responsible for pollution. By reducing the level of energy you use on a regular basis, you can help cut back on pollution. This includes using energy-efficient appliances and turning them off when you arent using them.
Filling a gas tank during cooler evening hours cuts back on air pollution.
By filling your tank during cooler times of the day, less gasoline evaporates into the air, reducing pollution. It also helps to avoid spilling gasoline by not topping off the tank and replacing the gas tank cap tightly.
