Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem physical systems or living organisms.
Pollution can take the form of chemical substances or energy, such as noise, heat, or light.
Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels.
Pollution is often classed as point source or nonpoint source pollution.
Sources of Pollution
1. Anthropogenic (Human Caused) Sources of Pollution
Agricultural - comprises wastes, emissions, and discharges arising from farming activities.
Industrial - pollution which can be directly linked with industry, in contrast to other pollution sources. This form of pollution is one of the leading causes of pollution worldwide.
Transport (Car, Ship, Airplane)
2. Natural Sources of Pollution
Volcanic eruptions - An eruption begins when pressure on a magma chamber forces magma up through the conduit and out the volcano's vents. When the magma chamber has been completely filled, the type of eruption partly depends on the amount of gases and silica in the magma. The amount of silica determines how sticky (level of viscosity) the magma is and water provides the explosive potential of steams.
Dust storms - As the force of wind passing over loosely held particles increases, particles of sand
