Pollution caused by ICT ( information communication technology ).
This presentation contents is Much more explanatory full of animated gif and picture you can explain it in your own style
(not like ordinary only Point readout presentation).
Explanation depends on your own creativity
6. Space debris
(Orbital
debris/Space
junk)
⊙ Collection of defunct object in orbit
around earth.
⊙ This include every thing from spent
rocket stages,old satellites,fragments
from disintegration, erosion and
collision .
7. Bring the attention of your audience over a key
concept using icons or illustrations
Years agoNow DaysCompletely INACTIVE Satellites
9. White
Is the color of milk and
fresh snow, the color
produced by the
combination of all the
colors of the visible
spectrum.
Risks
Black
Is the color of coal,
ebony, and of outer
space. It is the darkest
color, the result of the
absence of or
complete absorption
of light.
10. Energy
Consumption
⊙ 5% of the worldwide primary energy consumption is
caused by ICT (production, use and end-of-life)
⊙ Expected: 10% in the next 10 to 15 years (if no precautions
are made)
⊙ 9% of ICT consumption is caused by the wireless access
networks.
⊙Energy consumption within wireless access networks.
⊙ 10% consumed by user terminals such as mobile phones,
laptops, etc.
⊙ 90% consumed by base stations.
12. ⊙Addition of excess undesirable heat to water that makes it
harmful to man , animal and aquatic life
⊙ After the water is used, it is put back into a water supply at
9-20oC warmer.
Thermal
Pollution

13. ⊙ Thermal Shock: A sudden thermal shock can result in mass
killings of fish, insects, plants or amphibians.
⊙ Oxygen dissolved in water is decreases.
⊙Causative agent of Global warming .
Risks
14. ⊙This is the pollution due to abnormal radiation in the
environment. This occurs due to use of radioactive elements
from atomic energy stations.
Radiation
15. ⊙ Researches tells teenagers have four to five times more
disease in less than 10 years. Exposure to radiation from
cellphones.
⊙ It has been observed that birds like sparrows and insects like
honey bees seem to be getting extinct from human areas due
to these radiations.
Risks
16. ⊙ Also known as
Photo pollution or
luminous pollution.
⊙ It is excessive or
obtrusive artificial lights.
Light
Pollution
A comparison of the
view of the night
sky from a small rural
town (top) and
a metropolitan
area(bottom). Light
pollution dramatically
reduces the visibility
of stars.
17. ⊙ Light pollution effects
especially disturbing to
sleep of humans, birds
and other animals.
This might some times
affect the natural body
rhythm or circadian clock.
⊙ Prolong exposure to excessive light may lead to vision
problem.
