    2. Introduction Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Energy weSRCH

    5. What is Air Pollution Air pollution is the introduction of particulates, biological molecules, or other harmful materials into the Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. Air pollution may come from anthropogenic or natural sources. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has been recognized as a threat to human health as well as to the Earth's ecosystems. Energy weSRCH

    6. Causes of Air Pollution Burning of Fossil Fuels Agricultural activities Exhaust from factories and industries Mining operations Indoor air pollution Energy weSRCH

    7. Effects of Air Pollution Respiratory and Heart problems Global Warming Acid Rain Eutrophication Effect on Wildlife Depletion of Ozone layer Energy weSRCH

    8. Prevention Air Pollution Prevention effects of Company have generally focused on waste reduction, reuse and recycling So to solve these Problems and to get over them we can change our life styles. If we do these simple things we could have a better world. Energy weSRCH

Oceans, lakes, rivers, and other inland waters can naturally clean up a certain amount of pollution by dispersing it harmlessly. Energy weSRCH
