1.0 Introduction
The human population is increasing rapidly but advancement of technology is trying to keep up with the pace. By the increase of human population, the contact with the environment is getting more intensive, because human needs are increasing. And by the findings and development of new technologies, human can apply them to get what they want. And it's now understood and widely accepted that new technologies would bring their respective side effects besides their advantages. This clearly tells us that the back bone of man made pollution is the increase in population and technology. Pollution can also be caused naturally. This type of pollution does not cause excessive harm to our lives due to its regeneration ability; but, the man-made pollution harms a lot and is hard to get rid of. This report highlights the definition of pollution, the different types of pollution and for each type of pollution explains the causes, effects and solutions to prevent it.

2.0 Objective
The purpose of this report is to educate the community about the causes of pollution and what harm it can do to us and the environment we live in. To inform people the ways in which we are contributing in increasing the pollution. In addition to that, we are trying to encourage people to take simple steps to bring down pollution. And the purpose of the booth we are setting is to educate people through simple yet attractive posters, diagrams, pictures, props and flyers. Most people learn more by visual modes rather than written. For some of our props we have used recycled paper to show our support towards reducing pollution.

3.0 Definition of pollution
The Collegiate Dictionary (2003, p. 961) defined pollution as ” The action of polluting especially by environmental contamination with man-made waste.” Pollution damages the Earth's land, water and air. It results in contamination of the Earth’s environment with materials that are harmful for human health, the quality of life, and the natural functioning of ecosystems. There are many types of pollutions such as noise, light, thermal, water, visual pollution, radioactive pollution and many other types, but we can broadly divide pollution into three main categories, air, water and land pollution.

4.0 Air pollution
Air pollution is defined as “contamination of the atmosphere by gaseous, liquid, or solid wastes or by-products that can endanger human health and the health and welfare of plants and animals, or can attack materials, reduce visibility, or produce undesirable odors.”(The institute of earth and battle ground n.d.)

4.1 Causes of air pollution- Air pollution does not only involve the outside air, even the indoor air which is just as polluted, and maybe even more. That is one reason why it is important for everyone to learn more about the causes of air pollution 4.1.1 Automobiles- Driving a car is the most polluting act an average citizen commits. Particles of oxides of lead, nitrogen and sulfur released causes haze and smog resulting in the poor vision in the area. Combustion engines contribute to greenhouse gas accumulation in the atmosphere and are responsible for climate changes. 4.1.2 Fumes- Volatile organic compounds (or Vocs), come from paints, solvents, aerosol sprays, air fresheners, insect repellents and dry-cleaned clothing. If VOC accumulates in the house it is really harmful for the people living there. It combines with nitrogen oxide and produces ozone. 4.1.3 Industries- Industries are one of the main causes of air pollution. Industrial processes produce thick black smoke which emitted into the atmosphere without a proper filtering system leads to an increase of carbon dioxide. And their solid waste disposals can lead to strong odor and humidity, right conditions for pests and bacteria growths, which further aggravates the odor in the area. 4.1.4 Burning of fossil fuels- Among the gases emitted when fossil fuels are...
