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 .

WhiteIs the color of milk and fresh snow, the color produced by the combination of all the colors of the visible spectrum.

Risks

BlackIs 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.

Energy Consump

tion

⊙ 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.

⊙ 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 Pollutio

⊙ 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

⊙ This is the pollution due to abnormal radiation in the environment. This occurs due to use of radioactive elements

from atomic energy stations.

Radiation

⊙ 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

⊙ 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.

⊙ 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.
