3. POLLUTION
• Pollution is the introduction of contaminants into the natural environment that cause
adverse change.[1] Pollution can take the form of any substance (solid, liquid, or gas)
or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of
pollution, can be either foreign substances/energies or naturally occurring
contaminants. Although environmental pollution can be caused by natural events, the
word pollution generally implies that the contaminants have an anthropogenic source
– that is, a source created by human activities. Pollution is often classed as point
source or nonpoint source pollution. In 2015, pollution killed nine million people
worldwide (one in six deaths).[2][3] This remained unchanged in 2019, with little
real progress against pollution being identifiable. Air pollution accounted for ¾ of
these earlier deaths.[4][5]

4. TYPES OF POLLUTION
NOISE POLLUTION
• Noise pollution, also known as
environmental noise or sound
pollution, is the propagation of noise with
ranging impacts on the activity of human or
animal life, most of them harmful to a
degree. The source of outdoor noise
worldwide is mainly caused by machines,
transport, and propagation
AIR POLLUTION
• Air pollution is the contamination of air due
to the presence of substances in the
atmosphere that are harmful to the health of
humans and other living beings, or cause
damage to the climate or to materials.
