Air Pollution and Acid Rain

Air Pollution

• Definition: Unwanted chemicals, gasses, and particles entering the air and atmosphere, causing harm to animals and damaging Earth's natural cycles.
• Natural Causes: Volcanic eruptions, dust storms, and forest fires.
• Human Causes: Factories, power plants, cars, airplanes, chemicals, spray cans, and methane gas from landfills.
• Burning Fossil Fuels: Major human cause, releasing gases like smog.
• Effects on Environment: Global warming due to excessive carbon dioxide in the atmosphere.

Natural Causes of Air Pollution

• Volcanic eruptions: release large amounts of ash, gases, and particles into the atmosphere.
• Dust storms: lift dust and sand particles into the air, causing pollution.
• Forest fires: release smoke, carbon monoxide, and other pollutants.

Air Pollution

• Causes: Global warming, damage to ozone layer, acid rain
• Effects on Health: Difficulty breathing, lung cancer, respiratory infections, heart disease
• Impact on Children: Especially dangerous in cities with bad smog
• Air Quality Index: Government's alert system to measure air pollution

Causes and Effects

• Air Quality Index: Government's alert system to measure air pollution

Air Pollution

• Sulfur dioxide: Generated by burning coal or oil. Causes acid rain and respiratory illnesses.
• Carbon dioxide: Released when fossil fuels are burned. A greenhouse gas.
• Carbon monoxide: Produced by cars. Odorless and deadly.
• Chlorofluorocarbons: Used in devices, caused ozone layer damage.
• Particulate matter: Tiny particles in the air.

Clearing the Air

Reduce air pollution by using less energy and driving less. Turn off lights and electronics when not in use. Talk to your parents about carpooling and planning errands efficiently. Facts: London experienced the Pea Soup Fog in the 1800s. Road transport is the biggest polluter. Clean Air Act improved air pollution in the US. Los Angeles has the worst air pollution. Air pollution can cause eye irritation and difficulty breathing. Indoor air pollution can be worse than outdoor pollution.

Road Transport

Road transport is the biggest contributor to air pollution. It releases harmful pollutants like carbon monoxide, nitrogen oxides, and particulate matter. To reduce pollution, consider using less energy, driving less, and turning off lights and electronics. Together, we can make a difference!
