Light pollution is a global issue and the situation is becoming worse by the rapid use of LEDs.

LEDs were designed to be an energy-efficient lighting device that could minimize the energy impact for the planet, however, LED is rich in blue color and is quite harmful for astronomy, health and the nature.

The speaker will also talk about different dark sky actions that could be act on, including his own example in the heavily light polluted city - Hong Kong.
