There are valid arguments on each side of the "light pollution" debate. Astronomers dislike stray light that makes it difficult to see the stars, while police and city planners - and residents - know that street lighting and security lighting deter criminals, who would rather practice their vile trade in the dark, and makes it safer for drivers. So the question is, is there a way to light the cities, but not the skies?
There is no escape. Light bounces, reflects, scatters. You can't point lights at the ground and not have reflections back into the sky. Which is not to say that engineers can't try to minimize the effects.
Many street lights and city lights point UP. This may be pretty, but does nothing to enhance security while magnifying the problems of light pollution. Street lights and security lights should be shaded to not point to the sky.
Really, though, it boils down to a decision about who gets inconvenienced; a few astronomers, or millions of citizens?
Go out of the city so you can see the stars the only way to not have light pollution is to turn them all off
It can be prevented by stopping pollution...
DONT DRIVE YOUR CAR!
Reduce the number of humans on the planet.
THEY HAVE PREVENTED BY, PLANTING TREES ALONG RIVER BANKS, CONSTRUCTING TALL CHIMNEYS, NOT BURNING PLASTIC OBJECTS
You could stop pollution and littering
it could reduce pollution and renew energy resources.
Light pollution is not a crime yet, but buildings should atempt to reduce it. Light pollution is still a crime against the environment.
Light pollution does not affect astronauts, it affects astronomers.
hire people to first beat up the pollution to a higher platform, then people up there beat it back down.
in electroplating their is production of fumes and this fumes are prevented from getting the environment trough passing them through perflouracarbons .But remember that one form of preventing pollution can led to another for of pollution.
Light pollution and air pollution effect astronomy by making it more difficult to view the stars. If you notice, when you get out of the cities where there is less air and light pollution, you are better able to view the stars.
Some FALSE facts on light pollution are: 1. Astronomers benefit from light pollution as it helps them to study stars. 2. All stars are visible in the night sky when viewed from a light polluted city. 3. Light pollution is good for the environment. 4. Light pollution doesn't affect human sleep cycles.
