Title: What is Pollution?


1
Pollution
2
Defination
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.
3
There are actually SEVEN different kinds of
environmental pollution. Most people can name
air, water and land...do you know the other four?
Or examples of what constitutes actual pollution
in each category
4
  • 7 Kinds of Environmental Pollution
  • Air Pollution
  • Land Pollution
  • Light Pollution
  • Noise Pollution
  • Thermal Pollution
  • Visual Pollution
  • Water Pollution

5
Air pollution
According to the dictionary, air pollution is the
contamination of air by smoke and harmful gases,
mainly oxides of carbon, sulfur, and nitrogen.
(And maybe by that smelly uncle.) Some examples
of air pollution include Exhuast fumes from
vehicles The burning of fossil fuels, such as
coal, oil, or gas Harmful off-gasing from
things such as paint, plastic production, and so
on Radiation spills or nuclear accidents
6
Land Pollution
Land pollution, in other words, means degradation
or destruction of earths surface and soil,
directly or indirectly as a result of human
activities. Anthropogenic activities are
conducted citing development, and the same
affects the land drastically, we witness land
pollution by drastic we are referring to any
activity that lessens the quality and/or
productivity of the land as an ideal place for
agriculture, forestation, construction etc. The
degradation of land that could be used
constructively in other words is land pollution.
7
Light Pollution
Light pollution is the brightening of the night
sky inhibiting the visibility of stars and
planets by the use of improper lighting of
communities. Some examples of what causes light
pollution Street lamps that shine light in
all directions, instead of with a hood to point
light downward toward the street. Extra,
unnecessary lights around the home Cities
that run lights all night long
8
Noise Pollution
  • Noise pollution can be disruptive to humans'
    stress levels, may be harmful to unborn babies,
    and drives animals away by causing nervousness
    and decreasing their ability to hear prey or
    predators. Air pollution is linked to asthma,
    allergies and other respiratory illnesses. You
    can more about how the environment affects human
    health here. Land pollution is the degradation
    of the Earth's surface caused by a misuse of
    resources and improper disposal of waste. Some
    examples of land pollution include
  • Litter found on the side of the road
  • Illegal dumping in natural habitats
  • Oil spills that happen inland
  • The use of pesticides and other farming
    chemicals
  • Damage and debris caused from unsustainable
    mining and logging practices
  • Radiation spills or nuclear accidents
  • save envirement neat clean and lives happy

Thermal Pollution
Thermal pollution is the increase of temperature
caused by human activity. A few examples of this
include Warmer lake water from nearby
manufacturing (using cool water to cool the plant
and then pump it back into the lake) Included
in thermal pollution should also be the increase
in temperatures in areas with lots of concrete or
vehicles, generally in cities Noise pollution is
any loud sounds that are either harmful or
annoying to humans and animals. Some exmaples of
noise pollution Airplanes, helicopters, and
motor vehicles Construction or demolition
noise Human activities such as sporting
events or concerts
10
Visual Pollution
Visual pollution is an aesthetic issue and refers
to the impacts of pollution that impair one's
ability to enjoy a vista or view. Visual
pollution disturbs the visual areas of people by
creating negative changes in the natural
environment.
11
Water Pollution
Around half of all ocean pollution is caused by
sewage and waste water. Each year, the world
generates perhaps 510 billion tons of industrial
waste, much of which is pumped untreated into
rivers, oceans, and other waterways.
12
Pollution prevention reduces the amount of
pollution generated by a process, whether it is
consumer. In contrast to most pollution control
strategies, which seek to manage a after it is
formed and reduce its impact upon the environment
the pollution prevention approach seeks to
increase the efficiency of a process, thereby
reducing the amount of pollution generated at its
source. Although there is wide agreement that
source reduction is the preferred strategy, some
professionals also use the term pollution
prevention to include pollution reduction.
