Natural Sources

An exisiting creatures on earth may cause air pollution becaus of their nature. As example, volcanic eruptions, wild fires, and allergens. These natural sources produce toxicated smoke which can degrade the air quality and resulting air pollution.

Human Activities

There are different types of human made air pollution.

• Greenhouses gasses

  In order to produce energy, fossil fuels or coal are needed to be burn. The burning activities produce greenhouse gasses into the air such as carbon dioxide, methane, nitrous oxide and flourinated gasses.

  
  

• Smog

  Smog often seen produce by huge production of factory. Two types of smog which are

  • Sulfurous

    This type of smog is made up by sulfur oxides. Occured when burning sulfur barring fossil such as coals for industrial usage and energy production.

  • Photochemical

    This smog occurs when the sunlight, nitrogen oxides and volatiles organic compund reacted together. Nitrogen oxides are from coal power plants, factory emissions and vehicles exhaust.

    
    

2. Air Pollution effects on human health

   Air pollution that causes by smog as example, will resulting a haze. Thick haze can irritated human eyes, difficulty of breathing and cough for most cases. If the air quality continues polluted because of the human activities, it will led to deathly disease such as lung cancer and eye cancer.
