We often hear about air or noise pollution, but how many of us know about light pollution?
More than a half of world's population is living in cities and have never seen the Milky Way in their life.
In India, our cities are highly polluted with unnecessary light which is not needed and ends up wasted up in the air. Light pollution grows at 2% annually across the country.
Light pollution is a major concern for our human health. It disturbs our circadian rhythm/biological clock and adversely impacts our eyesight and well-being.
Mammals, reptiles, insects, birds and bats suffer a lot due to the increasingly bright nights. Light disrupts their reproduction, predation and migration.
We also end up wasting valuable resources, energy and money by putting on light where it is not needed or not using the lights correctly. Many street lamps light up the sky instead of our streets.
Night time construction activities with an abundance of lightning are a great disturbance to both humans and animals.
