Nights are getting brighter : The light pollution

   As we have begun working in night too, excess light is dumped into the environments at nights. This is endangering ecosystems and harming animals. This is because their life cycles depend on dark. We are endangering ourselves by altering the biochemical rhythms.

The International Dark Sky association defines light pollution as the excessive use of artificial lights. Though it is not as toxic as the air pollution or chemical spill, it is now one of the chronic environmental distresses.

Light pollution is increasing at the rate of 2% per year. We are moving towards more bright less energy lights. For instance LED lights. Recently Los Angeles replaced all of its street lights to LED lights. By this it is saving $8 million and is conserving 40% of energy. But the environmental costs to be paid for the move have increased. This is because LED lights are brighter.
