Review on Harmful Effects of Light Pollution
Abstract: For many decades we have seen increasing levels of light at night. People who are living in urban areasare spreading out of lights at night. Rapid growth of population and urbanisation in the world hasresulted more people are now experiencing light pollution without ever realising it. Variousdevelopmental activities and economic growth contributed to a sweeping increase in artificial lightusage, which further polluted the natural dark sky. The light pollution can …
